"Virtual" VFO for the Tablet PC operators (Futuristic Visionaries) ?

Like many of us who have visions of the future concerning the User Interface I am hoping for some good focus on the touch screen tablet aspect. While using the smartSDR preview in this way in "mouseless finger mode" so to speak some functions such as precise frequency tune & button size etc could considered. A pop "virtual" Flex control would also get rid of the "it wont sell without knobs skeptics". MAKE NO MISTAKE THIS WOULD BE A COUP FOR FLEX ELIMINATING THE KNOB ARGUMENTS FOR ALL TIME. Dan Toma's pocket multimode Transceiver for android boasts a virtual vfo tune that has sensational ergonomics & look.
