My first experience with HTC was when I flashed a Touchflo rom into my windows 6.5 Omnia. I really liked the using touchflo and have been trying to recreate that in my Droid and Droid 2.
I went from the Omnia to the Droid Eris. I barely used that phone. It was good but I really wanted a Droid with a keyboard. I soon got the Droid and I was expecting to find a sense UI for it my sadly thats not the case.
I really like the sense UI. The Blur UI is not nice and the widgets are OK at most.
For now I have a Droid 2 which I'm happy with but my next phone is probably going to an HTC. I just need to find one with a keyboard because I like playing games on my phones specially fighting games.
