I really hope they add a keyboard with better arrow key/home/end/pgup/pgdn keys at some point. This is literally one of the most important factors for me in a laptop because I hate the way most laptops do them.
Obviously there's a lot of danger to their own business model if things go that way, as there was for IBM back in the day. I want to believe they are aware of and ok with that though.
I do really wish they had macbook-like arrow keys, which are very effective for touch typing since the half-size makes them easy to feel.
