I love the nipple mouse. I find it much less irritating on my wrists than a trackpad. Plus, it allows for a rapid transition between keyboard and mouse.
I agree and I have disabled the trackpads in the bios settings for both of my Lenovo laptops. I just wish they could solve the slight movement drift you experience sometimes when using the ThinkPoint.
Yeah, it'll do that because it's used to your finger being on the stick and thinks that's the neutral position. It's supposed to stop and recalibrate itself eventually, especially when it reaches the edge of the screen. I've never had that take more than a dozen seconds on my Thinkpads (X31, T60) but of course YMMV, yours might be actually buggy.
