Hi! Sorry if this is the wrong forum. I wanted to post it in the audio subforum but as I'm talking about hardware I put it here! I'm buying a Macbook Pro to complement my recording setup. I have a beefy Win7 PC and it works wonderfully, but I want to expand my horizons and add a Mac with Logic so I can get experience with both. As I mentioned, I have a desktop computer so the Mac HAS to be a laptop, so please don't reccomend the iMac! If I was a rich man I'd buy a bigass Mac pro So, what it burns down to is, is there a massive difference in performance with the 13 and 15 inch? I'm assuming they both use onboard audio from intel or similar. Would the 15 inch be more able to handle a multitrack recording as opposed to the 13? I'm not too fussy on screen size, I just need to make sure that if I go the cheaper route I'm not missing out (much) on performance. Thanks for any help you may give!
