I got to play a little today with the new Nokia 7200 (for work research purposes... of course). If you're considering it, definitely try before you buy. It's a capable device by anyone's standards, and unless you're desperate to make use of 3's video-calling, you'll find it the smallest and lightest option for 3G in the UK right now.
Jakob Nielsen's "Top Ten Web Design Mistakes of 2003" exposes some real bugbears that I can completely sympathise with, particularly with respect to credit card entry fields.
