That's a cool looking little machine. What would be not only the primary use, but anything you'll need to do from time to time? If you just want a portable little system for some documents, email, browsing, and perhaps a little Photoshop from time to time.. it looks cool, but the specs don't show an HDMI output, so you'd need to get a USB-HDMI adapter for Mac if you want to hook up an external monitor at home (and with a 13in screen, you probably will). You'd definitely need external storage unless it'll be a straight email/doc/browsing machine.
I'm with @
Peally with the Apple disdain. They're overpriced for what they are. The key factor for Win/Apple is whether you need to run high end commercial applications such as Photoshop or absolutely need the newest MS Office. Linux really can't compete in that arena, though native Linux apps are improving all the time.
