If your question is "is it usable?" then answer is yes, it is. If your question is "worth it additional money I have to pay over the regular notebook?" then the answer actually depends on what you expect from TabletPC. If you are a businessman, willing to eliminate paper and user computer only, then the TabletPC is the only way to go, as you may use it to take notes during meetings, and it's much more affordable than regular notebooks for that. It is also convenient to read internet sites laying on the sofa. However, there is a price you pay besides additional bucks. First of all, be aware that TabletPC has to be tiny, otherwise it will be to heavy to keep on one hand when using another for writing. This means it has a limited battery capacity, which means that you will probably get at most 2 hours of continuous operation. And secondly, they have limited set of ports and relatively small screens.
