I think his issue with the alt key is valid. If you're using this keyboard with a Mac you will use that key as the Mac command key. Since it's the most frequent shortcut key used, it should be convenient to press. There's really no need for the space bar to be so large (it does not have to be as small as the japanese keyboards). The command and spacebar key placement on the MacBook seems to be perfectly fine.
