I got my 7100v in September and loved it despite a few teething problems which I guess were due to having very early models. By December I was onto my 4th unit and that one was great. But, I get serious gadget bordom and decided to go for the 7290 a couple of weeks ago.
I love the 7290 just as much. Bigger screen, excellent keyboard and all the apps seem even better. The only thing that takes a bit of getting used to is the phone. Not quite as simple to use as the 7100v. But hey, lot's of pro's, so I'm happy.
