I'm interested to know people's views on which would people go for and why - the iPAQ 5550 or the XDA2?
I have vast quantities of contact information (not just numbers but history too). Much of the information is sensitive, also having made do with the Palm Vx for years, I want to get "connected" - so Bluetooth/WiFi is a must for connecting to phone and home network (but would it be better to have the phone built in?).
Compact Flash would be a nice to have, and I know the iPAQ has an expansion sleeve - but with the release of 512Mb SD cards, I'd be happy to drop that requirement.
I use a company mobile phone (it's Vodafone), so I have limited flexibility over contract.
So do you want a device that has a built-in mobile phone? The XDA II is a Pocket PC Phone Edition and makes sense if you'd like to combine a Pocket PC and mobile phone in one unit. The iPAQ 5555 is just a Pocket PC (no phone). If you want a phone, the XDA II certainly makes more sense. But if you're happy connecting via a WiFi access point at home/work/public venues that offer the service or via BT and your BT mobile phone, then the iPAQ 5555 is certainly a nice PPC.
