I was messing around with an app called lockbot or lock 2.0 yesterday, and somehow while the phone was "locked" I switched from Sense UI to pure android. At first I was baffled at how my phone did this while it was supposed to be locked, but then I figured out from the lockbot/lock 2.0 lock screen you can open up a wide variety of menus. I guess I managed to hit the secret code. Anyway, I figured while I have Android running I would try it out. I really love it. The Eris seems to be much smoother on every app I try. Even the "call end" button seems to take faster. I love Sense UI, but I love the performance my phone has right now. And I managed to fit everything I "needed" onto the 3 provided screens. I am going to continue testing the phone without Sense, but I was curious if anyone had any things to look out for that could help me determine wether or not I should return to sense.
