I have the NP900X3C-A04US which is similar, but has slightly upgraded specs. > Ubuntu 12.04.1 installs & runs without modification, but some minor Fn keys didn't work (e.g., WiFi toggle button). This doesn't even work on Windows without their crap-ware. I made a copy of their installation files, uninstalled it, and now run it only when I need to use those FN keys (that is - very rarely). Other than this and the 4GB of RAM ... this is absolutely the most perfect laptop I have ever put my hands on and even beats out the Apple MacBook Air (which I sold after getting this).
