Overall Review: Everything was working great for about two weeks before the USB ports would suddenly completely stop working. Right smack in the middle of work, I couldn't use the keyboard and mouse, even though the computer was on and operational. After several days of trying to get a solution I couldn't put any more time on it because work was starting to pile up. I returned it and got a full refund. Asus says it's a software issue and they may have already put out an update for it but I couldn't wait any longer. Definitely check to see if the update was issued.
