Anyone seen any reviews for the HP Split x2?

Haven't seen a single thing about this, but was wondering if I'm just missing something because it's already been for sale for a couple weeks. I know it's from HP (yuck), but it seems to me like it could be the most compelling option for a "true W8 device."

Anyway, has anyone seen any kind of detailed info about this PC? (even just battery life/hands-on/benchmarks)
