I'm a fan of the Ubuntu OS, but I wouldn't shell out $600 for vaporware. Once it is released and certified as a quality product, I will buy one.
This. I can't believe anyone would consider shelling out $600-800 for what is essentially a proof of concept, with no real evidence of functionality. No specific details on CPU or battery? You guys have much more faith than I do.
And expected delivery of May 2014--when was the last time you saw something similar actually launch when expected? I'd wager nobody will see theirs before end of 2014, if then.
