I am rough with mine (my first uses were on some IBM tank from the late 80s/early 90s when I was young and a Lenovo T61 in college). Spurious clicks and taps happen all the time when I end up using the things. I have spent minutes trying to get an Apple trackpad to perform to drag and drop and instead having it do every other thing from extra clicks on the way to zooming to running out of space when I get to the edge trying to get where I'm going. The fact that you can SSH in and use a more exacting interface is the best feature of the things IMO, but sometimes the UI is just the only way to get something done.

I also liked the matte texture of the ThinkPad, but I think that era is over (the XPS isn't glassy like Apple's at least, but still lacks texture).
