Summary: okay so i just sold my Samsung Infuse and went back to the HTC Inspire. This phone is amazing.. HTC Sense is by far the best UI on any phone. it has been upgraded to Android 2.3.3 I had the Infuse for a bout a month and there were things that just didn't sit well with me. touch wiz is complete crap compared to Sense. i love how the HTC inspire feels and conforms to my had as where the Infuse was too blocky for me.
Pros: Pretty user friendly. Draw a custom design to unlock your screen is cool. Great picture and video capturing. Tons of free apps to try out before you purchase them. HTC Sense feature ties contacts to FB, Twitter, Google, etc., etc.
Cons: Battery life sucks, just like the iPhones people. Get used to it for now. Gorrilla glass WILL break and WILL scratch. Use protection. Rear facing speaker is hard to hear when watching videos.
