My ipad hasn't replaced my laptop (I got an Macbook Air 11 for that) what it has replaced is all the other crap I used to carry around when travelling - books, media, stuff I did on my phone but is much nicer on a big screen, music making tools (actually I couldn't do this on the move prior to the ipad). I recently completed a two day trip abroad with my Tom Bihn satchell , ipad , laptop, wires and a couple of clean shirts (ironed using the 'hot shower' classic)
