LOVE the HTC Radar!!
Great battery life!, not too bulky, very responsive touchscreen, fast browser, speech texting and calling
No WiFi calling, marketplace needs to get more apps&games.
The Bottom Line:
If you are working your way from a blackberry to a touchscreen, Id say this is the way to go!
I upgraded to this phone about a month ago after having been a loyal BlackBerry device user for a few years. I can honestly say this was the best decision I made:) At first I had a few difficulties being that there isn't a physical keyboard but before I knew it I was texting like a pro. The phone is pretty great at fixing typos so you don't really have to worry about that. In case your wondering battery life on this is great which is a HUGE plus for me! Also the camera isn't bad at al for a 5mp, and I almost forgot to mention video chat through tango is awesome! (you first have to download the app through the marketplace)
For me, the one downside is the fact that the HTC Radar doesnt support WiFi calling. With my Blackberry I was able to use WiFi calling whenever I traveled to a place that pretty much had no cellular reception:( This isnt a big enough reason for me not to love this phone though.
One more things that can be a downer for some, if your huge on apps and games, Marketplace still is a bit backed up when is comparance to Android or Iphone, again not a bit deal to me.
