Anyone can give me a reason, other than cost why instead of purchasing the iPad dock w/keyboard is a better option rather than just purchasing the iPad dock (already bought one, I need another) and then purchasing a bluetooth keyboard? I would think buying the dock and separate keyboard would be more versatile. Just out of curiosity, I don't know if I'm missing a feature with the one iPad w/keyboard dock. If not, then I'm going to purchase another dock and a bluetooth keyboard. I could always use a bluetooth keyboard. Thanks in advance.
