Well I sold my Droid for $315 and grabbed the HTC today!! So far I love it! So much smaller and lighter than the Moto which is great for me since I carry in my pocket! The phone is very similar to the Droid minus the keyboard and weight. Phone is very fast but so is the Droid. 7 screens is a plus!
I am a novice user just getting used to the android base but I say the main difference between the phone for a novice like me is the basic appearance. I prefer lighter phones and did not use the physical keyboard of the Droid which is why I switched. Personal preference is what it comes down too.
