This plays into the argument that the iPad is a toy -- I disagree with this. Firstly that was the critique aimed at the first generation of PCs back in the day -- they were hobbyist's toys and if you wanted to do real work use a mainframe. Next I've seen friend in the real world who attach a keyboard and park themselves at coffee shops and get actual work done. One should also keep in mind that this is the first generation of these devices, my bet is that we're at the very start of a real change.
