I bought a desktop with a touchscreen...

I never use the touch screen as it is quite awkward to use. The screen is a 23" so sits back on my desk and I have to lean forward to touch. Mouse and keyboard is much easier. Also as I leave my computer on at night it is sometimes woken by flying insects which then proceed to open programs and create havoc. I happily use my iPad and phone touch screens but would never buy another desktop with one. I'm happy with my Sony laptop touch pad and have never felt the need of a mouse or touch screen. Mind you I have stuck with Win 7 so with Win 8 I may feel differently.
