Who's playing Rocksmith via Boot Camp? #1: I've read it's a decent way to learn guitar: true or false? (I know what a chord is and can even play a few but need some reinforcement beyond a book) #2: How much storage to allocate to a Boot Camp partition containing Rocksmith + DLC? #3: Am I likely to experience technical or performance issues on an MBA 2011 or 2012? Thanks!
