REVIEWS OF WINDOW CE OS

It can be difficult to take a pick between Windows Embedded CE 6.0 and the previously-used Windows CE operating system. The best way is to compare the features, applications and tools of the two. The sixth release of the Windows operating system, Windows CE 6.0 is an extremely useful and highly efficient system as compared to the other previously launched similar applications. It provides a high quality features to software developers. With the help of this embedded system developers can easily create the application as well as the operating system using a single environment. Besides this, the paper also elaborates on the various features of this new embedded operating system and what are the qualities that make it different and more useful as compared to the existing operating systems. There are several major changes in features and applications of the Windows CE 6.0.A renewed version of kernel that can support around 32000 processes which is very high as compared to the earlier application that only enabled kernel to extend its support to 32 processes at a time. Coding and creating new applications has been made extremely easy with this new system. This operating system uses a special device based on ARM that enables the users to configure and test new applications and operating images before releasing and also make the required changes at any stage. This paper lists several such advantages of using Windows CE 6.0 over the earlier operating systems.

The Pocket PC is an evolution from previous 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 capabilities. The Hp 95LX and Hp 200Lx series packed a PC-compatible DOS computer with graphics display and QWERTY keyboard into a palmtop format. The Omigo 100 used a pen and graphics interface on dDOS, but was not widely sold in the United States. The HP 300XL 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, after the Pocket-Rocket.

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 $800 USD 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, whilst bearing the phone operator's logo, are actually 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, 336MB of Memory (256MB Flash, 64MB SDRAM), integrated 802.11b and Bluetooth 1.2, integrated Intel 2700G multimedia accelerator with 16MB 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, 2200mAh also available).[6]

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,[7] a high-end Pocket PC with a VGA screen and an integrated SiRF Star III GPS; the HTC TyTN,[8] a small communicator with integrated slide in keyboard; the HP hw6945 and HP iPAQ hw6515 with integrated thumb-board, GPS and GSM/GPRS telephony;[9] 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).[10]

A newer entrant into the Pocket PC market is Palm which sells devices like the Treo 700w/wx[11] 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, responsible for manufacturing up to 80% of all phone enabled Windows Mobile devices for other companies (including HP and O2) as well as many non-phone enabled Pocket PCs (for companies such as Dell, HP and Fujitsu Siemens), are now marketing Windows Mobile devices under their own brand (such as the HTC Touch), as well as that of Dopod.[12]
