well for what its worth the N900's touch screen is excellent, I work in a phone shop can have tried them all.

Yes personally i think capacitive is better than resistive but its all about the end user, not all capacitive screen are good, my HTC Hero's touch screen was beyond rubbish and my wifes Blackberry Storm is quite possible the worst phone ever made, while iPhone's screen was fantastic.

My advice to you or anyone is to pop into a shop and ask for a demo with the phone, its all about whether 'you' can use the touch screen, not whether you next door neighbour can use it. Even if its considered a bad touch screen i.e. N97, if you can use it and like it, then a better touch screen i.e N900, iPhone might not suite your style of operation..

I've served people who cant use an iPhone but are fine with a Nokia 5530 or Samsung Tocco Lite..

Better ain't always 'better' - if you know what I mean
