I'd go for the hx2110 because:
- it also has a CF slot
- much as it's "only" 312 MHz, the speed difference isn't that big
- it has WM2003SE, as opposed to WM2003
- it has a new BT Widcomm stack that can be upgraded to the latets goodies (Wi-Fi headphone, see
http://www.pocketpcthoughts.com/foru...c.php?p=319797 ). The 2210 can't.
- the 2210 won't likely get any upgrades any more; the hx2110 is a newer and current model, so it may even receive the WM2005 upgrade (but I woulnd't bet my life on it, knowing HP's recent upgrade policy history...)
BTW, if you're European, why don't you get a local (meaning: because of the lack of customs, far cheaper) model? The Pocket Loox 420 is exactly the same as the iPAQ 4150, and, except for being a bit aged (BT isn't upgradable, WM2003 only), and the lack of CF, it has Wi-Fi, which can be much more useful than e.g. WM2003SE.
