Actually character recognition is really good especially with the newer Windows 7 tablet interface. Besides it is/was not a choice between full-fledged performance and touchscreen capability. HP hybrid tx2000 series tablet pcs are regular fully-powered laptops that double as tablets. It makes sense when you need to read and annotate a lot of documents or take notes. There's also the fact the most laptop owners have access to a powerful desktop when they need to do heavy-duty creative/productive work.
Having said that, the older tablets had terrible screens in terms of readability. I am looking forward to a tablet hybrid that uses Pixel Qi screens
