Heheh, I´m bored so I decided to put my MacBook Pro to the limit, both cores 100%, 1100mb (out of 1280) of RAM used up, hardrives and fans spinning like crazy and my desk about to melt yet the machine is still very usable even with Finder, Dashboard, System Preferences, Safari, Firefox, Mercury, Acquisition, Pixen, Quicktime, iTunes, iPhoto, iMovie, iDVD, iWeb, GarageBand, PhotoBooth, Keynote 3, Pages 3, Microsoft Word, Excel, Entourage, Microsoft Messenger, Parallels (running an instance of WinXP Pro!), Mactracker, Calculator RPN, Grab and Preview, yet I can still use the computer as normal, who needs Merom? The power is right here with Yonah lol I love my MacBook Pro very much, very impressive considering its running a lot of demanding UB apps, a resource hungry translator (rosetta) and a few PowerPC apps and its running another OS as well!
