IMHO, tablety paddy things are all just expensive toys unless they let you use some form of accurate stylus as well as your fingers. Fingers have some major usability issues if used as your only drawing instrument, when it comes to any form of detailed technical drawing, and in engineering environments are often covered in various interesting varieties of minging filth. Also, we can see down to a much finer point than the tip of a finger and even if I have paid out serious money for something that calls itself a 'retina display' I would still like to be able to try and see which pixel it is I am selecting.
