Thanks very much for all the replies guys.
I've been umming and urring about which way to go.
I currently use (much as one) my laptop, a PDA (HP Jornada) and my Nokia 6310i. I use the full functionality of each one, and want to try to combine them in a decent PDA-style phone. Hence why I'm seriously considering the P800. Following from all your comments above i'm near enough certain I'm gonna get one. I've had Nokia's since I've had mobiles (1997) so am a little un-easy about changing brands as I've grown so used to the Nokias.
Just a few questions I have though....
1) It doesn't have nokia-style profiles, what does it have or how do you get it around (i.e. does it just have normal and silent mode?)
2) Where did you get the screen protector from? I read on forums that people tend to take the keypad off and use the touch-screen numbers, but means it can get scratched easily in the pocket. Where did you get it, and how much was it?
3) I've played with one in an Orange shop for about half an hour, but obviously it's not like really owning the phone. Does anybody have any criticisms of the phone? For example, I know that the volume you set your phone at is the volume the alarm will go off at - eg, if it's silent, no alarm!?! Also, the alarm wont activate if the phone is turned off. Just little things like that!??
Thanks very much to one and all.........you've been a great help
