As PDA phones go, this is/was one of the better ones. I have also used Blackberrys and the older Siemens units (SX55 and SX66) and this was probably the best overrall. The OS is now a little bit dated, but the core functionality is still very good. The unit is a near-perfect size for a PDA phone, with a screen that isn't too big or too small. It is not the fastest in terms of the Edge connections (slower than a 3G iPhone) but when using WiFi you should be fine. The bluetooth works great and I was even able to connect a BT stereo headset with no problems. There is a slot for a flashcard if you want to listen to mp3's (wired or wireless headphones)and the GPS works great, even though the battery drain is pretty bad with everything switched on. In the car, I try to leave it connected to the car charger. The MS apps work fine and I have never had stylus/screen trouble. Not a lot of room for onboard apps, but if you install to the flashcard you will have plenty of room to add Opera etc.Pros:-Good balance of size/weight-WiFi built-in-Bluetooth-Full browser (pocket)-Good screen brightness/resolution-any stylus will work fine-card slot-excellent keyboard-works in EuropeCons:-pricey-a little power hungry (for medium/heavy useage you will need to charge every night)-slower than current PDA phones-OS is a little dated now
