I need to get a touchpad that I can use while I go to some of my long doctors appointments. I want one that has a USB port for thumb drives, can play movies and music, connects to the internet, and I can use as a reader. It would be great to have one that I can also attach an external keyboard as well. I need the best value that is something I can afford. Any ideas? I can go for a new or used one, so any feedback would be great.
