how good is the phone quality on 7290 vs 7100?

Just moved from a 7100t to a T-Mobile 7290 this afternoon.

Initial impressions are that the 7290 seems to do a little better with signal reception than the 7100t. Not a huge difference, but our data center at work is in a weak signal area, so any little bit helps.

I'll try to remember to post another comment after a few days of using it.
