IPAQ is a product line of personal digital assistants (PDAs ), which were originally manufactured by Compaq. Since the acquisition of Compaq by Hewlett -Packard sold under the HP label.

The operating system is Pocket PC or Windows Mobile of Microsoft is used, which is similar to using the familiar Windows operating systems from desktop PCs. It is operated via a touch screen, frequently used applications are placed on separate hardware buttons ( eg, calendar, contacts, etc. ).

Prior to the acquisition of Compaq HP had their own PDAs under the model designation Jornada on offer. After the acquisition, these models have been replaced by the Compaq iPAQs. This surpassed by its great expandability in the professional environment simply more options.

HP is increasingly difficult in 2004 as part of its iPAQ product line in criticism, since no updates were available on current operating system generations. As an argument, HP introduced here on, among other things, that an adaptation of the software on existing devices ( were meant devices that were a year or longer on the market, so all hitherto produced devices) is not desired by a majority of users and you doubted that users were willing to pay the high demand at the low price. Previously, slightly after the release of the operating system Windows Mobile 2003 SE, Toshiba had already for the products e400 and e800 primary, which at the time of the main innovation, support for VGA displays, benefited published upgrades.

In 2005, HP announced an upgrade to the now current version 5.0 of the Windows Mobile operating system for the product series hx2100, hx2400, hx2700 hx4700 and. After a delay the upgrade for the iPAQ hx4700 any upgrades were available for around 50 € in September 2006.

After HP has now been taken over Palm and its WebOS and Microsoft Windows Mobile in favor of Windows Phone 7 stopped, no further iPAQ models on Windows Mobile are expected to base.


Prior to the acquisition of Compaq iPAQs were delivered with an extended interface. It made it possible to expand with so-called Sleeves (also called Jackets ) the PDA. These are brackets into which the PDA can be inserted and set the various functions. There were Sleeves with Compact Flash slot and PCMCIA slot (also dual PCMCIA slot ) and two sleeves each versions with and without integrated battery. Later versions with Bluetooth, VGA port, GPS and other enhancements have been developed.

From the H3800er generation of the docking port has been revised and is up to about 2007 remained the same. This allowed the use of old hardware to new devices. However, the positioning of the PDA makes occasional problems, so that the hardware would indeed work electrically, but not physically fit and demands something of customization work. In addition, some series do not have a serial port. HP has turned the connector 180 degrees with these devices.

As of 2010, all models use a mini-USB port, only the iPAQ 200 series has a second, enhanced connectivity among other things, contains a USB host interface. At least for the PDAs iPAQ series, there are currently no HP Docking Stations more.

The operating system is at the iPAQs Windows CE or Windows Mobile from the hx2xxx models used. Since the hx2190/hx2490 and models hx2790 Windows Mobile 5.0 pre-installed, which is usually ( as here ) flash memory instead of RAM used by which stored on the device data is no longer lost when the battery is empty.

Alternative operating systems

Although the original state, the Windows Mobile operating system is installed, there are also Linux ports as angstroms or Familiar Linux, the GPE Palmtop Environment, Qtopia and OPIE as a graphical user interface. Likewise, NetBSD and Plan 9 has been ported to the iPAQ.


The iPAQ models were meant just in the early days for professional use. The large expansion options, straight through the PCMCIA sleeve, this has been underlined. Thus, it was possible to use conventional laptop technology directly into a PDA. Only the driver had to be adjusted. Some manufacturers offer still on devices to connect iPAQ devices, for example, directly with GPS, instruments, tactical ( military ) radios, wireless and modem or upgrade with hard drives, digital cameras, RFID-Lese/Schreibgeräten. Many of these enhancements are now available for other PDA. The iPAQ was not the first PDA that offered this extension diversity, but it was the device that was the first such a high spread that this was attractive to manufacturers. There are also manufacturers who package the iPAQ inner life in industrial grade housing and market under our own product name. Consequently, these devices are suitable for IP54 or even suitable for hazardous applications.

Film and Television

Again and again, even devices H5500 and h5400 series in various films and television series, see again. For example, in CSI: NY and CSI: Miami, or a Compaq iPAQ 3800/3900-Serie in Nip / Tuck - Beauty has its price.


The following list is sorted by date of sale. The models up to and including the iPAQ 3900 are still Compaq - labeled, but were driven already by HP. The iPAQ H5450 was the first production unit with HP logo.

The hx2790 is basically a hx2750 was at the RAM replaced by flash memory and Windows Mobile 5.0 instead of Windows Mobile 2003 was used. For the hx2750 there was a WM 5.0 update.

Note to the Bluetooth Stack: Widcomm Broadcom has taken over, so the Broadcom stack used in the HP versions is a further development of the Widcomm stack.
