A Pocket PC

A Pocket PC

A Pocket PC (P/PC, PPC) is also known by Microsoft as a 'Windows Mobile Classic device'. It is a hardware specification for a handheld-sized computer, personal digital assistant (PDA), that runs the Microsoft 'Windows Mobile Classic' operating system. It has some of the abilities of modern desktop PCs.

As of 2010, thousands of applications exist for handhelds adhering to the Microsoft Pocket PC specification, many of which are freeware.^[1] Some of these devices are also mobile phones. Microsoft-compliant Pocket PCs can be used with many add-ons such as GPS receivers, barcode readers, RFID readers, and cameras.

In 2007, with the advent of Windows Mobile 6, Microsoft dropped the name Pocket PC in favor of a new naming scheme. Devices without an integrated phone are called Windows Mobile Classic devices instead of Pocket PCs. Devices with an integrated phone and a touch screen are called Windows Mobile Professional devices and devices without a touch screen are called Windows Mobile Standard devices.^[2]

History[link]

This unreferenced section requires citations to ensure verifiability.

The Pocket PC is an evolution from prior calculator-sized computers. Keystroke-programmable calculators which could do simple business and scientific applications were available by the 1970s. In 1982, Hewlett Packard's HP-75 incorporated a 1-line text display, an alphanumeric keyboard, BASIC language and some basic PDA abilities. The HP 95LX, HP 100LX and HP 200LX series packed a PC-compatible DOS computer with graphics display and QWERTY keyboard into a palmtop format. The HP OmniGo 100 and 120 used a pen and graphics interface on DOS-based PC/GEOS, but was not widely sold in the United States. The HP 300LX built a palmtop computer on the Windows CE operating system, but not until the form factor and features of the Palm platform were adapted that it was named the Pocket PC.

Prior to the release of Windows Mobile 2003, third-party software was developed using Microsoft's eMbedded Visual Tools, eMbedded Visual Basic (eVB) and eMbedded Visual C (eVC).^[3] eVB programs can usually be converted fairly easily to NS Basic/CE.^[4] or to Basic4ppc.

Definition[link]

According to Microsoft, the Pocket PC is "a handheld device that enables users to store and retrieve e-mail, contacts, appointments, tasks, play multimedia files, games, exchange text messages with Windows Live Messenger (formerly known as MSN Messenger), browse the Web, and more." (src: microsoft buyersguide)^{[dead link]}

From a technical standpoint, "Pocket PC" is a Microsoft specification that sets various hardware and software requirements for mobile devices bearing the "Pocket PC" label.

For instance, any device which is to be classified as a Pocket PC must:

• Run Microsoft's Windows Mobile, Pocket PC edition
• Come bundled with a specific suite of applications in ROM

Note: the name Windows Mobile includes both the Windows CE operating system and a suite of basic applications along with a specified user interface

• Include a touchscreen
• Include a directional pad or touchpad
• Include a set of hardware application buttons
• Be based on an ARM version 4 compatible CPU, Intel XScale CPU, MIPS CPU or SH3 CPU. (As of the Pocket PC 2002 specification, ARM-based CPUs are required.)

Operating system versions[link]

Windows Mobile 6.5[link]

The first Windows Mobile 6.5 device was first shown on September 2009. Leaked ROMs surfaced in July 2009 for specific devices.^[5] The generic ROM images for Mobile 6.5 are also available as part of the officially distributed and freely downloadable development kit.^[6]

Several phones running Windows Mobile 6.1 can be updated to Windows Mobile 6.5.^[7]

Windows Mobile 6.1[link]

Microsoft's current Windows Mobile release is Windows Mobile 6.1, and one of the major changes from Windows Mobile 6 is the introduction of instant messaging-like texting.^[8] Windows Mobile 6.1 was built upon Windows CE 5.

Windows Mobile 6[link]

Microsoft's Windows Mobile 6, internally code-named 'Crossbow', was officially released by Microsoft on February 12, 2007. Mobile 6 was still based on Windows CE 5 and was effectively just a face-lift of Windows Mobile 5. With Mobile 6 also came Microsoft's new naming conventions and devices were no longer called Pocket PCs: devices with no phone abilities were named Windows Mobile Classic, and devices with phone abilities were named Windows Mobile Professional.

Windows Mobile 5[link]

Windows Mobile 5 for Pocket PC was based on Windows CE 5 and contained many fixes and improvements over Windows Mobile 2003.

Pocket PCs running prior versions of the operating system generally stored user-installed applications and data in RAM, which meant that if the battery was depleted the device would lose all of its data. Windows Mobile 5.0 solved this problem by storing all user data in persistent (flash) memory, leaving the RAM to be used only for running applications, as it would be on a desktop computer. As a result, Windows Mobile 5.0 Pocket PCs generally had more flash memory, and less RAM, compared to earlier devices.

Windows Mobile 2003[link]

Windows Mobile 2003 consisted of the Windows CE.NET 4.2 operating system bundled with scaled-down versions of many popular desktop applications, including Microsoft Outlook, Internet Explorer, Word, Excel, Windows Media Player, and others.

Windows Mobile 2003 Second Edition added native landscape, square screen and VGA support as well as other fixes and changes to those features already present in the original release of Windows Mobile 2003.

Windows CE 3.0[link]

Pocket PC 2000[link]

Pocket PC 2000 was launched April 2000, and ran Windows CE 3.0. Pocket PC 2000 featured a mobile version of Microsoft Office, a chief feature being the ability to password-protect Excel files.

Pocket PC 2002[link]

Pocket PC 2002 was launched October 2001, and was powered by Windows CE 3.0, as with its predecessor. Some Pocket PC 2002 devices were also sold as "Phone Editions", which included cell phone functionality in addition to the PDA abilities.

Pocket PCs are manufactured and sold by several different companies; the major manufacturers include HP (under the iPAQ and now defunct Jornada brands), Toshiba, Acer, Asus, Dell (under the now defunct Axim brand), Fujitsu Siemens, E-TEN, HTC, and ViewSonic. In Mid-2003, Gateway Computers and JVC announced they would release Pocket PCs, but the projects were discontinued before a product was released. Prices in 2003 ranged from around US$800 for the high-end models, some of which are combined with cell phones, to $200 for low-end models. A $100–$200 model was rumored to be released within 2004 or early 2005, although the lowest price for a just-released Pocket PC never went under $300. Many companies ceased to sell PDA's by 2003–2004 because of a declining market. Major companies such as Viewsonic and Toshiba stopped producing new Pocket PCs.

Before the Pocket PC brand was launched, there were other Windows-based machines of the same form factor made by HP, Philips, and others called Palm-size PCs. These devices ran Windows CE 2.0–2.11 and had an interface that was similar to the then-current desktop versions of Windows, such as Windows 98.

Companies like O2, T-Mobile and Orange are marketing Pocket PCs that have integrated mobile telephony (smartphones). All users have to do is put in the SIM card and follow the wizard, to put their SIM contacts in the address book. An example is O2's Xda, or T-Mobile's MDA Compact. Both of these devices, while bearing the phone operator's logo, are manufactured by the dominant Pocket PC manufacturer HTC.

One of the more popular high-end consumer-market Pocket PCs was the Dell Axim x51v, which was discontinued in 2007. Hardware specs included 3.7" color TFT VGA display with 640x480 resolution, Intel XScaleTM PXA270 processor at 624 MHz, 336 MB of memory (256 MB flash, 64 MB SDRAM), integrated 802.11b and Bluetooth 1.2, integrated Intel 2700G multimedia accelerator with 16 MB video memory. Expansion was possible via CompactFlash Type II and SD slots (supporting SDIO Now!, SDIO and MMC cards). Included is a 1,100 mAh user replaceable battery (est. 4-6.5 hours, 2200 mAh also available).^[9]

Some Pocket PCs feature integrated GPS often combined with mobile phone functionality. Pocket PCs with built-in telephony differ from Windows Mobile Smartphone Edition devices in several respects, including the lack of a touchscreen on the latter. Some examples of current Pocket PCs with GPS integrated are the Fujitsu Siemens Pocket Loox N560,^[10] a high-end Pocket PC with a VGA screen and an integrated SiRF Star III GPS; the HTC TyTN,^[11] a small communicator with integrated slide in keyboard; the HP hw6945 and HP iPAQ hw6515 with integrated thumb-board, GPS and GSM/GPRS telephony;^[12] the HTC top of the line Universal, branded as the QTek 9000 (also branded by various telecommunications companies as the Orange SPV M5000, T-mobile MDA Pro, Vodafone VPA IV, O2 Xda Exec, i-Mate JasJar, Dopod 900).^[13]

A newer entrant into the Pocket PC market is Palm which sells devices like the Treo 700w/wx^[14] based on Windows Mobile 5.0 and featuring integrated telephony. Previously, Palm only produced PDAs running the Palm OS (as did the first versions of the Palm Treo) and still sell versions of the Treo based on the Palm operating system.

HTC manufactures up to 80% of all phone enabled Windows Mobile devices for other companies (including HP and O2), as well as many non-phone Pocket PCs (for companies such as Dell, HP and Fujitsu Siemens). HTC is now marketing Windows Mobile devices under their own brand, as well as that of Dopod.^[15]

It has been suggested that Coat pocket be merged into this article or section. (Discuss) Proposed since July 2010.

A pocket is a bag- or envelope-like receptacle either fastened to or inserted in an article of clothing to hold small items. Pockets may also be attached to luggage, backpacks, and similar items. In older usage, a pocket was a separate small bag or pouch.^[1]

Origins[link]

Pockets hang from belts as 15th-century peasants thresh siligo wheat in a Tacuinum Sanitatis

In European clothing pockets began by being hung like purses from a belt, which could be concealed beneath a coat or jerkin and reached through a slit in the outer garment.

The word appears in Middle English as pocket, and is taken from a Norman diminutive of Old French poke, pouque, modern poche, cf. pouch. The form "poke" is now only used dialectically, or in such proverbial sayings as "a pig in a poke".

Historically, the term "pocket" referred to a pouch worn around the waist by women in the 17th to 19th centuries, mentioned in the rhyme Lucy Locket.^[2] Also called a hanging pocket.

"Pocket" is also a term for a sack in which hops were stored, generally with a capacity of 168–224 lb (76–102 kg).^{[citation needed]}

Types[link]

A watch pocket is a small pocket designed to hold a pocket watch, sometimes found in men's trousers and waistcoats and in traditional blue jeans.^[3] A besom pocket is a pocket cut into a garment instead of being sewn on. These pockets often have reinforced piping along the slit of the pocket, appearing perhaps as an extra piece of fabric or stitching. Besom pockets are found on a tuxedo jacket or trousers and may be accented with a flap or button closure.^[4] Camp pockets are pockets which have been sewn to the outside of the garment. They are usually squared off and are characterized by seaming.^[5][6][7]
