"Real simple: what's the best Core i5 or Core i7 13-inch laptop (with discrete graphics) for running both Windows 7 and Mac OS X? I'm a video and photo guy who does marketing work for a university, and while I've been using a Dell M1330 to operate on both sides of the fence, I'm in dire need of a hardware upgrade. I'm not fussed by the Windows vs. Mac debate and use both on a daily basis, but I need as much power as possible in an ultraportable form factor in order to handle both of these operating systems (sorry, 13-inch MacBook Pro, but you aren't cutting it). Here's hoping your readers can help out!"
