I'm fed up. I have a MacBook Pro (2.5Ghz, 4GB RAM), my partner has a Black MacBook (2.4Ghz, 2GB RAM). At the moment I'm using both to rip "24" series 1 using HandBrake - both have the same settings and are doing nothing else. My partner's MacBook finished whilst my MacBook Pro was still doing title three of four. It's more than 25% faster!! Not to mention the fact that his MacBook has been flawless whilst I've had to have the keyboard and the battery replaced due to faults. Furthermore, the MacBook's 10month old battery still has 99% health, my four week old, newly replaced, 11 cycles battery is already down to 97% health. Why the hell did I bother paying the extra for the 'pro' version when the MacBook is, from what I can see, a more capable machine?!
