In addition to that you don't really know what the market it going to look like 2 to 3 months from now when this ships. Apple, Asus, Dell and others could very well have a tablet in the market by then. So even if you were willing to chance losing your money entirely it wouldn't make sense to buy one of these.
If the tablet's software isn't 100% open-source and hackable, I'd be worried on the long-term support from Fusion Garage.
