Hey guys i just joined the forum seeking some advice from you seasoned professionals. I just graduated school and the sony vaio desktop i have had throughout school (a little over 4 years) finally died so i am in the market for a new computer. This is the one I am looking at: http://store.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?nplm=FA878LL/A Is it worth going with the aluminum over the old white ones? Should i get a 20" with a faster processor? Any comments, tips, suggestions are welcomed and appreciated!!! Thanks.
