Okay, here's the deal. I need a new notebook, and I'm pretty set on the MB. It'll be for both work and play. I'm an IT Guy, so it'll be used for connecting to systems, switches, routers, blah blah... Checked the refurb, and they have a base MB/2.0 for $849, a White 2.2/$999, and a black MB 2.4/$1299. I realize the black is the best one, but based on my needs, what will give me the best bang for the buck???
