Just watching the video (no sound)...
#) A lot of space that looks like it could be used for bigger keys is empty.
#) It's about 1" deeper than the Apple, for no evident reason, which means it may not fit the tote bags etc designed for the Apple unit.
#) It's hard to open, even with two hands.
Those are just easy negatives, and none are major. I think it's great that Asus is producing this and have had very good luck with their products (a motherboard and a netbook).
