Unless you can't stand OS X. Also the "Better Trackpad" is arguable. And I'll take the Pixel's screen.
MagSafe is a big draw though, arguably as important as almost anything else. Comparing the screen on my MBA to the screen in the new Dell Developer laptop with IPS is a bummer though.
In all honesty, I've never even seen a USB3.0 device in the wild either. Not an argument against the option, of course.
Nope, Ubuntu 13.04 works perfectly out of the box on my Air. With older versions you have to install more stuff to make sure the fans kick in, etc.
edit: Actually, hotplug Thunderbolt is touchy in Linux 3.8 because Apple's thunderbolt implementation is back-ass-ward stupid, but that's not really a biggie, I don't use Thunderbolt for anything really (the display out is fine)
- Thunderbolt
- USB 3.0
- Bluetooth 4.0
- Optical In/Out
- MagSafe
- Better Trackpad
Not to mention a company with a history of great support. There really isn't any good reason to buy a Pixel.
