Over the past month or so, every now and then it will just shut off when I'm running too many things at once (and even sometimes when I'm not). Or sometimes it'll just go to sleep for now reason. So I guess I need to start preparing for it to die right? I guess that would entail a few things: Backing up all my data - All my important stuff is on Dropbox or I could pull it off my iPod. I don't want to just plug in a hard drive and take everything off the laptop because I don't want to put all the crap I have on it on to my next laptop too. So I guess I'll spend an hour or two sorting between what I want and what I don't. But I have a few questions. 1.) iCloud - I have iCloud activated, but I don't ever seem to see it do anything. I have iTunes Match so I'm guessing I could re-download anything on there on to my new Mac without having to back that up. But as far as pictures go, are those all stored somewhere that I can re-download? 2.) When I log into the new laptop, will I just be able to re-download any apps I've got from the Mac App Store? And as far as picking a new laptop is concerned, I think I want to go with a MacBook Air. But is the processor going to be good enough? I rarely do anything very taxing on the processor outside of watching video and occasionally editing some.
