Hey guys, so I've been flip-flopping back and forth between a base 13" MBA w/8GB of ram and a base 15" MBP. After heavily browsing/posting in these forums and watching some youtube videos, I think I've finally settled on the MBA with upgraded ram. I realized that I wouldn't need all the "oomph" that the pro provides. After looking at the costs of purchasing an aftermarket SSD, optibay, and ram, the price differential is even greater between the MBA and MBP. With that being said, I'd like to purchase an external USB drive for more storage. I have a lot of music and games that I know wouldn't fit on the internal SSD. Down the line, I'll probably upgrade the SSD but right now, an external solution would suit me best. Just a couple questions, is it possible to run windows 7 off an external drive? I know USB 3 definitely has lower bandwidth when compared to the read/write speeds of the internal drive. But if I stored some programs on the external would they run noticeably slower in comparison?
