sony ericsson is ideal if you have patience with tinkering gadgets -> using every feature it can offer and are willing to spend more on accessories.

but if you're always on the go and you got used to nokia for 6 months or so, stick to nokia.

ako kasi I've owned and tried all, SE P900, Palm PDA, IPAQ PDA, Nokia Symbian Phone. guess what i'm using right now, just a 6230. no smartphone capabilities.
I found peace here hehehe. but then again, that's me.
