Opening programs can be buggy at times where the system just hangs for a few seconds.The built XBMC permanently hung the system when i tried exiting.Setting up bluetooth to pair with my beyboard with built in touchpad is so far a disaster.All of the above is on Ubuntu.

Great unit, arrives ready to connect and power up. After playing with the unit today I am really impressed with the hardware. You should only purchase this unit with some knowledge of ubuntu and certainly linux. The online manuals and such are a bit thin and you need some experience to read between the lines. Certainly a step up from Raspberry Pi but then not for the first time user.

This device has a very very limited use! If you are buying this to be used as a computer then perhaps you could just purchase a tablet. It will be much faster and will have a screen as well. This unit is an expensive toy.

Would have given 5 stars but could not understand why such a great device did not come with a power supply included.

Booted up promptly right into the Ubuntu GUI. Bought for investigating the Linux OS. Thank You for prompt shipping.
