A member of the MyDellMini forums has modded a Dell Mini 9 and turned it into a Tablet PC. Rob928 took the netbook, stripped the lid off and trimmed the hinges among other things. He used a "Honda Fun and Easy" solderless touchscreen kit to create the tablet. One issue that was found with the mod, is that due to the design of it, it can get a little hot. It loses it's heat through the keyboard but because the screen is basically upside down, the heat isn't ventilated. If that wasn't enough, he also added Windows 7 to the device, which is described as better for a touch screen device anyway. You can view photos of the various stages through Rob's Picasa account.
