I've never heard of this before, but from the looks of it, its just another laggy Chinese gadget.
Whether you like to tinker or not, wait for that Raspberry Pi computer to come out and pair it with a nice big monitor. $25-35 little flash drive sized computer that can run on a lightweight distro = win. I'll let the link do the talking (in case you havent seen it before)
Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte!
Edit: a more convenient link, the wiki
