I have HP Touchpad tablet with Touchstone wireless dock - and I can't stress how awesome it is to be able to just put it down on a stand near my bed and not have to look for one of the two USB cables (because tablet requires more power than my phone, I need to pick the right one), just plop it down and it charges.

And same thing in the morning - I don't have to carefully pick it up, trying not to yank cord from charger, disconnect charging cable - just grab it, and go to bathroom.

And when I'm out of home, I can charge it with regular microUSB plug, but believe me, I curse it every single time.
