hey, I'm getting a 17'' MBP next week and need to get a carrying case (not just a sleeve/slip). I know there is a guide above this about buying one and where to get them from. But what I really want is someone's real life opinion. I would like one that could hold my laptop, as well as the power supply and everything comfertably, and if it could have enough extra space somewhere to hold an External Hard Drive, that'd be perfect! What do you all use?
