I have acquired a 2010 MBP (being shipped to be now) I have 2009 white / pre unibody MB and on this I have the soft Macally case. The laptop had this case on it since new virtually 95% of the time. Laptop shows some black marks on the corners from the case rubbing but no dents scratches etc. ----- My wife has a MBP with a hard plastic clear shell case. Is there anything else out there? Do the vinyl stickers work? Do they offer any protection? Are they total pita to install or install crooked? I'm looking for something more lightweight from my Macally soft case I have on my 2009. I do always carry my laptop in a computer / padded bag, unless I'm carrying the laptop itself in my hand.
