[SORTED] - HP Ipaq 214 usability with Arduino

Whilst I'm waiting for some parts to arrive for other projects, an opportunity has come up to buy an HP Ipaq 214 from my employer on the cheap. We have a bunch. I was wondering, apart from wanting a PDA for a while but not sure exactly what I'll do with it (its cooool to have toys) I was wondering if anyone knows if they can be interfaced with Arduino......AND by the off chance, if anyone has read about a hacked Ipaq running Linux or Android.

Thanks!

EDIT: Or should I rather find a used Android smart phone if I want to play with interfacing handheld devices?

you could connect to a arduino through Bluetooth and write some code to interface on the phone. it doesn't appear to have a serial port.
