I don't think they did much designing other than to take the atom reference motherboard and find a way to graft an ARM in there, all the rest looks like a dead ringer for the eee pc.

Build quality is something you can only establish by looking at the product and preferably disassembling it. Even then you still have to remember it's a statistics game, something may look excellent and yet it could fail miserably and in large numbers over a longer period of time.
