iPAQ presently refers to a Pocket PC and personal digital assistant first unveiled by Compaq in April 2000; the name was borrowed from Compaq's earlier iPAQ Desktop Personal Computers. Since Hewlett-Packard's acquisition of Compaq, the product has been marketed by HP. The device is the main competition to the Palm, but provides more multimedia capabilities and the familiar Microsoft Windows interface. Higher end units are very modular, having "sleeve" accessories which slide around the unit and add functionality like a card reader, wireless networking, GPS, and even extra batteries. These are technically called jackets.Note: PDAs branded "Pocket PC" run the proprietary Microsoft Pocket PC (Windows Mobile) OS. HPCs and HPC Pros run earlier versions of the OS, namely Windows CE.
Hewlett-Packard introduce the first SmartPhone iPaq Pocket PC that looks like a regular cell phone that can use VoIP. The series will be HP iPAQ 500 HP Press release.Contents [hide]

Model variations
Compaq iPAQ 3630
[edit]
Compaq iPAQ H3600 series
Compaq's flagship iPAQs were those of the 3600 models. Originally running the Microsoft Windows for Pocket PC 2000 OS, these devices featured 12-bit color displays, 32/64 MB of RAM, and 16 MB ROM.
Models in the 3600 series are:
3630, 3635, 3650 - which are identical models with 16 MB ROM and 32 MB RAM sold via different marketing channels. The 3635 was accompanied by a CF expansion sleeve that was sold separately with the other 2.
3660, 3670 - 64MB RAM. The 3670 was distributed in the US while the 3660 was distributed in Europe.
A Pocket PC 2002 OS upgrade is available, but the smaller ROM requires some software such as the media player to install in volatile RAM instead of the ROM as in the previous Pocket PC 2000.
As used units at low price, they are a great way to inexpensively get started with a PDA.
While limited by no on-board expansion slot, the iPAQ 3600 series memory and functionality can still be expanded by optional Compact Flash and PCMCIA sleeves, which allow users to add memory and peripherals. Some of these sleeves contain extra batteries to extend the iPAQ's battery life under the strain of added devices.

Compaq iPAQ H3100 series
This model was released after the 3600 series as a lower end & cost-effective model. It has a grayscale semi-transmissive STN LCD and only 16MB RAM. It had very limited success.

Compaq iPAQ H3700 series
These devices had the exact same form factor as their 3600 model predecessors, however, they had an increased ROM size and ran the PPC2002 OS natively.

The 3850 had 206 MHz StrongARM CPU, with 32MB ROM and 64MB RAM, 240x320 TFT screen, running Microsoft Pocket PC 2002.
