I have a P900 which is a great smartphone, but am still lookiing for a direct but enhanced (colour screen, integrated phone / wireless data) replacement for my trusty but now dead Psion, basically just becase it had such a usavbel keyboard and a wide screen for reading text without constant sideways scrolling.
I'm now looking at the Nokia 9500, looks a bit weighty but the keyboard and WiFi might swing it for me.
I would certainly go for Symbian based smartphones.
