I think you are missing a key benefit of tablet. People enjoy using tablets much more then PCs. PCs come with so much baggage, years of viruses, frustration, and required tech support. Also in my opinion, there is an intrinsic pleasure to using a touch screen versus a mouse. It helps that iPad apps tend to focus on aesthetics and the user experience. I think your view on consumption vs creation is based on the past. When the GUI first came out, the mouse was seen as a toy and not needed for real work. Now most creation needs a mouse. We create now with a mouse and a keyboard because it is what we had available. Creation is more than text entry and many people will find touch screens superior to a mouse for creation. People are already using an iPad for creation and apps will only get more powerful and useful. It doubt it will be long before tablets are better for graphic design, photo editing, and video editing.
