Sold without OS. I have installed debian Jessie / SID, without major problems. The webcam is not supported. Not having the utility, I have not attempted to resolve the issue. My use of the machine is: development with use of multiple VMs. I find the plastic a little cheap shell and the terrain too marked touchpad. For cons, the keyboard is really nice, precise strikes, fairly quiet, successful. Matte screen, for those who are not a fan of reflections. The sound is okay. I like less the weight (I had a 13-inch, say ...) and low battery ... (Less than 2:00 in normal use) It is possible the booster with 16GB of RAM, making it, despite small defects mentioned above, an excellent choice for those who want a powerful notebook computer with a quality / price ratio.
