1) 200gb at 4200prm, too slow vis-a-vis 160 at 5400. 2) what speed increase will come from a 160 at 720rpm? 3) will the default 128mb card diplay a 30" ACD fine? 4) what will the increase to 4gb of ram do for me from 2gb? I will be running maple, mathematica, and that's about it, really, that's intensive. oh and some C++ coding. (will do little 'documentary' type stuff for youtube, as well) 5) difference between glossy/matte? 6) any reason to get the 17" since I will be using a 30" monitor 70% of the time? 7) can any video card on the mbp allow for two 30" monitors? And if you want: 6) would you go with an ACD or the Dell 30" monitor? Thanks.
