zeph, actually the computer is now also much more Quiet!

When I had lots of applications opened on Rev1, then it would become slower and the performance would decrease.

Now there aren't any loud or busy sounding sounds =D

edit: I currently have 15 Applications opened, Installing an Adobe Suite, and I'm adding about 1000 songs to iTunes and browse the Web using Safari with many tabs open, and it's quite and everything runs like with zero apps opened :>
