I've been fantasizing about my switch a lot lately, and looking at possible candidates. I've been drawn toward the Macbook Pro, for its better features, Expresscard port, independent video card RAM, aluminum casing, etc. What I've been thinking most about is the specifications. I'd prefer a 15" over a 17", just because I don't think the extra $300 is worth the larger screen/extra ports/better DVD Burner. Additionally, it'd probably be less portable than the 15", but that's lower on the list. Anyway, here are two options I'm considering: MBP 2.0 GHz: 512 MB RAM (Can upgrade to 2GB @ somewhere other than Apple for $150-$175 or so) 80 GB HD (Upgrade to 100GB at Apple for $90, or can I do it elsewhere?) ATI Mobility Radeon - 128MB $1799 excluding upgrades, approx. $2065 with upgrades MBP 2.16 GHz: 1 GB RAM (Upgrade elswhere to 2GB for about $80) 100 GB HD ATI Mobility Radeon - 256MB $2299 excluding upgrades, approx. $2379 with upgrades When/If I do in fact get a Mac, it will be using the education discount, so that helps a little bit with the price, but it's still going to be tough to get enough to pay for one. I was wondering if anyone had any input on the differences in processor speeds/video card RAM, since those seem to be the only differentiating factors between the two computers. Is there any noticable difference between the two, and if so, is the price difference worth it? Thanks!
