In regards to the screen sensitivity with a protector, I imported a DuraSec HiTec protector from Germany and put it on immediately. This thing is still extremely sensitive to the touch, I almost forget it's resistive! I had both an iPhone and a Tilt for a substantial amount of time, and I rate the sensitivity with the DuraSec protector closer to the iPhone (love the very slight vibration/tactile feedback you get telling you've applied just enough pressure).

I am loving this thing!!
