Ugh, yes, I hate shopping for a new machine. It used to be ten times worse for me, because I used to build them myself. On the surface that may seem better, and yes it meant I could customize my machine, but it also meant I had many many many more decisions to make... argh! It drove me crazy after awhile, which was a large part of the reason I just started buying the mid-level Apple machine and ignoring all specs. I may not get the best value for my money anymore, but not having to make all these decisions is a huge weight off my mind.

Anyway, good luck!
