I bought a 6100 a few months ago and I'm happy with it. I picked it because of the battery life; I wasn't interested in having a camera or video. It's small, light, and inoffensive to look at.
I had a 7200 in my hand yesterday on the O2 Experience Store on Grafton st and the demo model in the shop looked very tattered due to the fabric cover.
The [broken link removed] stainless steel phone looks like a better bet to me.
