Like others have mentioned here, the Sculpt suffers from other issues apart from being wireless:
My biggest issue is the small, poorly constructed F-keys. Switching to regular sized keys on the Microsoft Surface Ergonomic shows how bad they actually are.
Anyway, is there a way we could get Microsoft to build a Sculpt v2 which fixes the shortcomings of the original one?! I still think it's one of the best ergonomic keyboards, even with issues it has.
