I own a 2007 macbook and don't see any real compelling reason why I'd continue to buy Macs to be honest. About the most intensive thing I'd ever need to do is some basic Photoshop, so these sub $1000 sub-notebook type systems seem really appealing to me. In fact I'd strong consider running Linux on it (and use GIMP instead of PS), although I'd need to dual boot for pokers.
