It's all personal preference; I like the AlBooks' keyboards better than any I have ever used, desktop or laptop.
I would caution, however, that even "like an hour" of typing isn't always enough to tell, especially with the amount of potential variables you've got being in a store (like body position). In my experience, switching to a new input device takes my body days to adjust. If you haven't been using a trackpad regularly, I suspect this takes some serious acclimation, but I wouldn't write it off after an hour personally.
As for "design," it is the same width as my Apple USB keyboard, and the wrist-rest area is typical of almost every laptop in existence. So I'm not sure what you mean that they should have designed differently ...
