This unit is VERY quick. Worked perfectly right out of the box. Needed to manually set up Microsoft Logon and connect to network drives that were not visible for some reason, but all in all, a very good little PC for a very reasonable price.I purchased to use as a Home Theater PC to stream stored video files. It worked flawlessly streaming videos along with the associated audio file. Just what the Doctor ordered :-0FYI: You must use the included power supply as a USB feed from the TV does not have sufficient voltage to operate. I have ordered, from Amazon, a 2nd power supply to make portability between TV's easier.
