Exactly. So many people focus on the consumer use cases, but I still feel like so many of the commercial ones haven't been realized yet. A failed startup I was part of in 2009 was working on a tablet app before iOS came out, and it was specifically for mechanical engineers and similar folks walking around buildings quickly, without having to stop and type on a laptop. Now I'm working on a tablet app to be used by nurses and doctors who are on their feet. No doubt there are numerous cases of people who need something they can use on their feet and who might also appreciate a slightly larger form factor than even a 6-inch phone screen provides.
