Ask Engadget: what's the best 13-inch Core i5 / i7 Wintel ultraportable for running OS X?

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Dan Murphy [great name!], who needs to know which ultraportable on the market today is best equipped to roll both ways... if you know what we're sayin'. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"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!"

We'd sure the master Hackintoshers out there would love to help out, and we're sure Apple will weep when realizing they'd have a sale if they would've crammed a Core i5 into their 13-inch MBP while refreshing the other guys last month. Go on, folks -- let this guy in on your secrets in comments below.
