"Powered by a 400 MHz Intel PXA255 XScale processor, the h5550 offers a good combination of raw power and sizeable on-board memory: 126 MB of RAM is available to users, combined with a beefy 17 MB of non-volatile storage. Battery life, on the other hand, suffers quite a toll as a result of the larger-than-usual display and wireless features. A continous audio stream from Windows Media Player with the unit's backlight off could only be sustained for just over 4 hours with default settings.

...

Equipped with both Bluetooth and Wi-Fi (802.11b), the h5550 offers unparallelled built-in connectivity support, and also offers tools that let users manage its features with relative ease. The range of included Bluetooth profiles is more than adequate, and the Wi-Fi portion comes with support for necessary security measures such as WEP and 802.1x - and combined with improved support in Windows Mobile 2003, such features are easier to use than ever before."
