Hi guys So, I just upgraded my 2006 Core 2 Duo MacBook (still a nice machine, handles Logic fine) to a 2011 15" MacBook Pro. Absolutely loving it so far... can hardly believe I'm hitting 7h:30m of battery life with a display that awesome and a quad i7 under the hood :O I'd like a 500GB 7200rpm HDD to improve boot times and program launching. I've been doing some reading, and I've been put off the Momentus XT due to reliability issues. But, I've also heard mixed stories about people noticing a big fall in battery life (1h 30m in one case) and only a modest performance boost with standard 7200rpm drives. There's a WD Black I think that everyone seems to like and I'm considering that. An SSD is out of the question due to the cost, I really need a minimum of 250GB - and more like 500GB as I have currently. My uses are: Steam, Logic Pro (recording, using Logic for the guitar amps and effects), MainStage, WaveBurner, occasional iMovie and all the other usual stuff everyone does on a computer. Thanks guys PS - Maybe we could sticky this, if it takes off with a lot of concise answers?
