CES (Consumer Electronics Association) was last week, and companies demoed a lot of really cool gadgets. One I think is worth sharing is a product by Tactus, a company in California. Tactus developed a screen that can turn into a flat tablet into something with actual bumpy buttons, to make it easier to type. When you’re not using the typepad, the buttons just disappear back into the screen, making it flat again. Click here to watch the video for more details–it’s pretty awesome.
