Under about this item it claims to have 3 USB 3.0 ports. It does not. One of the main reasons I purchased it, was because it said there were 3, which is important because I use adaptive keyboard, etc.  I had to return it, then was not refunded what I paid (though was well within 30 days) so had to follow up with Amazon for a full refund. In the about section:  "KISS DONGLES GOODBYE - With 3 USB 3. 0 ports, ExpressCard-54 slot, SD card reader, and a VGA port, you will be hooked up to whatever devices or accessories you need." I'm sure it's a very nice computer, if you do not need multiple USB ports. I really didn't want to have to carry a USB hub around too.
