The N900 is my first touch screen phone, and I've used a iPod touch before, and can honestly say those who say resistive is rubbish are talking rubbish!

Yeah, you need to press slightly harder, but it's nothing thats going to hinder any usage! Obviously I've never used other resistive screens, but the N900 one is superb in my opinion.. in fact I can actually type faster on the on-screen keyboard than the hardware one at the moment! The stylus comes in handy too.
