the macbook air is an awesome piece of kit, but its not a conclusive replacement for a macbook. its designed for road warriors, not everyday computer users or students (pricey!). so are apple likely to revamp thier existing macbook lines any time soon? i know the MBPs are expected/ruomred to have updates soon, but for the casual mac user they have to go for the macbook (which is starting to look old?!?). what does everybody think? when (or if) will apple release new macbooks?
