I have one, I love it. Running Linux Mint 15 with Cinnamon. One thing to watch for is that some kernel versions don't work well with the function keys or bumblebee (for optimus support). I'm running 3.9.4 now and it works quite well.

edit Also, I should add that I did spend the extra money to put a Samsung 840 SSD and an extra 8gb stick of ram in here

I'll vouch for the awesomeness of this exact laptop as well. I run linux in a VM inside it, though.

It's small, the resolution/screen is great, and has everything I need. I also upgraded the RAM and put in an SSD.

Yes. The screen is the best ever notebook screen i had.

After upgrading to 10gb RAM and SSD, it's a really good computer for developer.
