By the time you add keyboard, mouse and monitor it's not so small any more, and its useless without them. For a Windows CE device it's positively large. Much smaller PDA's and cellphones running WinCE / Windows Mobile-based OS have been available for years (and you dont need to lug around a monitor, keyboard and mouse to use them). And if it's designed to plug into a wall socket, it's not portable so there's zero reason for it to be small in the first place.
