I can't really disagree with your list, but I feel most of it demonstrates power user features rather than typical needs of a professional. I repeat my earlier point: I don't see much there that, for example, a graphic artist would demand. Very few people in the wider populace use multiple displays. Most people wouldn't know what boot control, background processes, or even filesystems are. Tab-order is screwed even on a 'real' OS like OSX. My main gripe is this belief that the iPad is somehow less capable because it doesn't run a 'real' OS when, in fact, it is usable precisely because it runs an OS tailored towards its purpose as a device for consumption, primarily, but also for specialised professional niches that don't involve tinkering under the bonnet for the sake of it — not that there's anything wrong with that, of course.
