yeah, great, just what i want to do, constantly wipe fingerprints off of my glossy screen.
also, i dont want to replace my 30" lcd with a 30" touchscreen. and if i did, i dont think i would want to lay it down flat. however, my arms would probably get tired with the screen mounted in front of me. geesh.
i like apple's approach with the wide multitouch, touchpad. much easier to keep clean.
