So...the new MacBooks have arrived and I can't decide between two of them! Here's my situation: Going to Uni to study Architecture in Sept '09. Will need a laptop (want a Mac) that can easily handle heavy CAD software (ArchiCAD/Vectorworks etc.), and that will last me for several years. Thinking of getting the top-of-the-line 15" MBP available at the time (there doesn't seem much point buying the top one now seeing as I won't need the graphics power for a year, and they don't include the latest CPUs (Centrino 2?), which should come later (?) to use with an external display when in my room. BUT need a laptop now for other work/internet/movies etc., and some fiddling around on my trial version of Sketchup to familiarise myself with the software, (i.e. doesn't matter if it runs a bit slow). AND would like an Al laptop (don't really like the plastic). SO, (sorry to ramble) do you guys reckon the 2.0GHz new MB would do me for the year? Or the 2.4GHz for better performance? (Would I notice?) Which do you think would be the most attractive second hand (say 10 months old)? I'm not usually one for the latest tech (I'm 18 and this is my first laptop for example), but I don't see the point in laying out a LOT of money for a MBP now when I'll only need it's abilities in a year's time. It seems that I could get the majority of my cash back on eBay when I sell the MB on (AND I'm buying with an HE discount=roughly 17% off). I'm just so confused- I don't want to buy the 2.0GHz and then be disappointed with the speed (I'm used to using the family pc which is E4500 @2.2GHz Core 2 Duo 539MHz, 2GB RAM). Advice much appreciated guys!
