There is a use for tablet PCs in the computer marketplace. That use is any job where you are required to be mobile as part of the job, yet also input data into a database at your "headquarters." (Example: Police officer, Industrial plants, Construction work managers, Truck drivers, etc.)
The problem, however, is application support for the device and user treatment of the physical hardware. Most "good" laptop owners would never dream of throwing their laptop into the passenger seat (like a paper log or small "rugged" handheld device) or leaving a computer in their vehicle overnight (freezing or very hot temperatures). Yet, in the occupations that could use tablets the most, they can't be used.
Further, the next question is whether we truly want them to be used. In the world of business, at least one person (if not several in a company/occupation) have no other job than data input from paper logs into databases. If we went to tablet use across most business fields, that is yet another occupation lost for the low and lower middle class across the country/world. (And, at the same time, creating jobs in all social economic classes... but these jobs are generally tied to specific areas known for computer expertise. Example: Silicon Valley, CA & India.)
