Remember the Friend's episode where Ross waxes nostalgic about his Casio keyboard from the 80s? Well, way back in the 80's, I had a little portable keyboard too, and sometimes, I miss the little bugger. Imagine how delighted I was to find this these virtual piano keyboards which work well with the touch screen on my Sahara Slate PC. Great for plunking out tunes! Best of all, they're free online applications. No downloads required!
