Accelerometer Accuracy

[hpmaxim]

I just got my TP2 yesterday to replace my old Mogul. After seeing the level application on an IPhone 3GS, I was hoping to see something similar on the TP2. Other than the G-Sensor calibration (which is rather crude since there are no numbers associated with it), I saw no other apps that are preloaded.

I installed Waterlevel 0.2, but I'm pretty disappointed with the performance. The resolution is almost 1 degree. The result don't seem totally repeatable. There seem to be dead spots (which go away when you flick it, which make me suspect it a software issue), and at large angles it seems to do weird things.

So, what's the deal? Is the accelerometer in the phone just crummy compared to the iPhone's, or is this a software issue? Is there a better software package available?
