Just got this beautiful one from work:
You can get all the details in the HTC website, but the quick and short details are that it's small, light, and has a cool 3D UI which IMHO gives iPhone a fair fight. Oh, and the telephony part is much better than my previous one, the Samsung Blackjack.
The downside is that it's a tad slow, and the battery life is not that great (probably a little more than a day, but mine is not a new device, as it's from work). I do however charge it during the day, when it's connected to my PC, and I also have a car charger, so it's not a problem so far.
The last issue is that it also takes time from the time the call comes in, to the time you hear the ring (2-3 missed rings), but this is the case with my previous Smartphone as well.
My recommendation? I think I'll wait a few days to decide. I only had it for about two days...
