Earlier quoted context omitted.
I am in the same boat. Received one at work and can not stand the keyboard. I requested an older model, but they are no longer providing them. It might seem dramatic, but I spend my days typing and I need my keyboard to not get in my way. I have resorted to bringing a USB keyboard into work with me.
To be fair, when you're actually in work, do you not find a less cramped keyboard, proper magic mouse (or magic trackpad) and dual monitors make you more productive? I know they do me.
I like Apple's trackpads, but the functions that they enable are merely nice-to-have features. If you spend your day typing, any noticeable drop in keyboard reliability is going to outweigh any other input-device productivity gain. Keyboard reliability is a critical showstopper feature.
