I'm looking for a combined phone and handheld. My wish list is
currently as follows:  - Bluetooth - WIFI, preferably a/b/g, b/g
will do - USB host support - Preferably IrDA - Serial interface
- Ethernet (can live without or by using some sort of dongle)
It seems the IPAQ hw69xx series is closest to my requirements,
but I'm unsure about the Linux support. It unfortunately
(according to hp.com's spec sheet) doesn't seem to have USB host
or another decent (PCMCIA or similar) extension slot.  I'm open
to alternatives. What is, or would be, important to me is the
possibility to have some sort of more in-depth control over it,
for instance to be able to implement a customizable screening of
incoming calls and text messages based on source number.  The
ability to run Linux on it and have all the hardware working is
important, however I could live with Windows Mobile for a while
as long as it's possible to modify/program it.  Regarding price
I won't decide on that until the alternatives are clear, but I
imagine $600
