HP iPAQ H1900 seriesAfter HP's acquisition of Compaq, the 1900 series was the answer to Palm's budget units. Adopted a smaller, slimmer frame making it more competitive in terms of portability. Main memory size was 64 MB, larger than all other budget units. Ran PPC2002 (1910 only) or 2003. Introduction of removable batteries, allowing for the user to buy extra batteries and swap as necessary. Unlike older iPAQs, many existing iPAQ accessories were incompatible or unsupported due to its budget nature.

HP iPAQ H5400 series
Introduced as the next generation of the iPAQ corporate line after the 3900 series, adding Wi-Fi support, improved Bluetooth and a biometric scanner. However, the 5400 was plagued with many bugs, though most were corrected through firmware upgrades. The CPU is the ARM-based Intel XScale PXA250.
[edit]
HP iPAQ H5500 series
A corrected version of the 5400 series with double the RAM (128 MB) running on PPC2003, PXA255 CPU.

HP iPAQ H5100 series
A cutdown version of the 5500 series, without Wi-Fi support and the extra RAM (only 64 MB).

HP iPAQ H2200 series
Targeting the general consumer/prosumer, the 2200 series is almost every bit as capable as their corporate counterparts (less RAM, no integrated Wi-Fi, no biometric scanner). Main memory size was 64 MB RAM, PPC2003, better support for iPAQ accessories than the 1900 series though still no iPAQ expansion "sleeve" support. Bluetooth, SD card and CompactFlash card support built-in. There is an advanced IR port built into the 2245 and 2210 models (and perhaps others in this series), and the software bundle includes a program which essentially turns this device into a universal remote control.

HP iPAQ H4300 series
Similar to the 2200 series in terms of features, the 4300 series targets the corporate audience by having a beefier battery and integrated Wi-Fi in addition to Bluetooth. No CompactFlash reader, but does have a SD-card and SDIO slot. A thumb keyboard is integrated into the device.
[edit]
HP iPAQ H4100 series
Essentially the corporate version of the 1900 series with many of the functionalities that were stripped from the budget unit. Also adds Wi-Fi and SDIO. Closer to the 4300-series internally. It came with PPC2003

HP iPAQ hx2000 series
Aimed at the business market, this series of PDAs sports built-in Wi-Fi, Bluetooth, SD Card and CF Card slots, and Windows Mobile 2003 SE. Some have included a Microsoft® Windows® CE 5.0 firmware upgrade disc. The different models have some different features.
[edit]
HP iPAQ hx21xx sequence
This series of PDAs sported only the barebones set of features listed above, and ran a slower 400 MHz XScale processor. No fingerprint reader and only 64 MB of memory.
[edit]
HP iPAQ hx27xx sequence
A very full featured business class PDA. Sporting a 624 MHz Intel PXA270 XScale processor, 128 MB of RAM and ROM (each), and a built-in biometric fingerprint reader, this model set is aimed at high-security and -performance enterpises. The fingerprint reader, with the proprietary HP ProtectTools software, can create "encrypted folders" in RAM or on storage cards (in these models' case, the iPAQ File Store, the SD Card, or the CF Card) to prevent anyone from swiping the memory cards and reading sensitive company-critical data. The processor, running at the aforementioned 624 MHz, helps with the encryption/decryption processes (HP ProtectTools can also encrypt the entire contents of the onboard memory).

HP iPAQ hx4700 series
The high end corporate edition to replace the 5500 series.
Sturdy magnesium alloy casing, 4 inch diagonal VGA screen at 65K colors, integrated Wi-Fi, Bluetooth 1.2, MMC and Secure Digital slot with SDIO, Compact Flash slot, 64 MB of RAM and 128 MB of ROM, with an Intel XScale PXA270 624 MHz processor.
It contains a 1800 mAh battery in the selling package with a removable 3600 mAh battery as an option. HX4700 is known as the first and only[citation needed] WinMobile PDA with 2 modes touchpad.
By design it is not compatible with previous IPAQ jacket accessories, but the proprietary USB connector at the bottom is still the same. It does not include leather or plastic case, but contains a removable screen cover instead.
Little known fact: Headphone adapter accepts 55xx series 4 pin plugs (microphone input)[citation needed]
HX4700 running Windows Mobile 2003 Second Edition at first release. There is a Pocket Informant 2005 integrated in ROM. Built-in encryption software also included. Can't run NEVO TV (remote control software) because it does not have Consumer IR. It contains Fast IR instead.
In April 2006 HP finally sells Windows Mobile 5 upgrade option for HX4700 users at their website. In this upgrade most of the additional software is also being upgraded including the Pocket Informant.

HP iPAQ rz1700 series
The HP iPAQ rz1700 series is a budget line, with Wi-Fi and IR transmission, as well as a USB cable. The devices run Windows Mobile 2003 SE and have 32MB of RAM.
The rz1710 does not include Wi-Fi.
[edit]
HP iPAQ rx4000, rx3100, rx3400 and rx3700 series
Billed as "Mobile Media Companions", some of these models feature Nevo personal media software, onboard 1.2 megapixel cameras (rx3400 and rx3700), Bluetooth, Wi-Fi, and an onboard Secure Digital card slot for extra documents or media.
The rx4240 and rx4250 are great medium entry PDAs: bluetooth, Wi-Fi, Windows Mobile 5, Mobile Office and heaps more are preloaded. The rx4000 range features a Samsung 400MHz Processor, and boasts a larger 128 MB ROM and 64 MB SDRAM, Up to 64 MB user-available memory on the 4240.
The rx3100 and rx3400 had 32 MB of RAM and 300 MHz processors, whereas the rx3700 had 64 MB of RAM and a 400 MHz processor. The latter also came with a 1440 mAh battery as standard, rather than the rx3400's 920 mAh unit.
These models have been known to suffer from a bug related to the way the iPAQ File Store, the rx3700's ROM, operates and manages files. This bug prevents the user from deleting or renaming files on the ROM, causing significant deficiencies in its operation. This bug is known by HP, but there is not yet an official solution for the problem.
The current version of the Windows Mobile 2003 SE operating system has been known to cause issues with Bluetooth functionality. Some patches have been released by the manufacturer, such as for Bluetooth headphones, but others, such as connectivity with HP GPS devices, have not been released. The devices continue to be non-functional for these models despite being published as compatible.

HP iPAQ h6300 series
Pocket PC Phone. Contains a GSM phone, 64 MB RAM, 168 MHz Texas Instruments OMAP processor, and comes with a detachable thumb keyboard. Also includes VGA quality camera and 1800 mAh battery. It has built in Bluetooth and Wi-Fi (802.11b).
T-Mobile used to sell the h6315 but has decided to withdraw it from the market. The firmware was never updated to remove all of the bugs which cause sporadic behaviour, including dropped calls, not answering calls, turning off, erasing all user memory (factory reset), etc.
Variants include the h6340 which is sold in parts of Europe without a camera through normal distribution points- hence is not carrier specific. The h6365 has identical specifications to the h6315 but it is not signed to a carrier.
[edit]
HP iPAQ Mobile Messenger hw6500 series
This iPAQ is the first Pocket PC phone to have built in Global Positioning System (GPS) capabilities with support for NMEA. When no GPS signal is available the device attempts to calculate its location by switching to cell triangulation. It has an integrated keyboard and unique 240x240 resolution. It may seem that the screen size can be an advantage regarding the standby time, but there are reports that actually many software products do not work on this device as they should because they were created for the standard 320x240 resolution (menus are not fully visible, hidden buttons- sort of problems).
It has two card slots SD SDIO and mini-SD and like its predecessor the h6300, two versions are/were available: one with camera and one without.
Most notably, compared to the previous model, this unit does not have internal support for WiFi.
Specifications can be found here.
This unit, as with most similar units, comes in a variety of languages. For a number of reasons, including the assurance of price in higher priced markets, languages are designed to not be changeable on the units. For example, if you have a unit with a German operating system, you cannot "officially" change the language.
The language can, however, be changed to English at this time by flashing the BIOS using upgrades released by HP.

HP iPAQ Mobile Messenger hw6900 series
These units entered the market in late 2006. Anticipated specifications can be found here (PDF)
Most notably, when compared to the previous model, this unit has internal support for WiFi as well as Windows Mobile 5. It also has a GSM phone, Bluetooth, and GPS built-in.
The IPAQ HW6915 is available in the market as of 2007.
