I haven't touched my laptop for anything except playing BF3 and Skyrim since I got my first tablet.
My wife hasn't touched her laptop since she got an iPad. I sold it to a buddy.
Once in a great while she does use the desktop computer that I built for her to use for her job for something not work related.
It has 2 24" screens, though, so no tablet is going to replace that.
Still pretty rare that she does that.
Of curse we have a 2 year old so free time is hard to come by. ;)
