My feet are killing me. I just finished a full day of press appointments at CE Week, a consumer electronics trade show. I was standing in heels while talking to members of the media about a new touchscreen product Westinghouse Digital was introducing. It is totally revolutionary and, right now, geared for the presentation market.

The presentation market is made up of educators, trainers, medical, and any other folks who need a big whiteboard for demonstration. Imagine a tablet on steroids. The touchscreen unit is available from 55-inch high-definition to a massive 84-inch 4K (UltraHD). The largest screen will set you back $15,000. All of the models are compatible with the latest Windows 8 and 7 operating systems. That means the info on the whiteboard can be downloaded to a PC or laptop.

The specs on the unit are so technical that it would be crazy to list here. Look at the pictures that accompany this story to get an idea of the capabilities of whiteboards. They are quite magical.

See what Gizmodo says about the screen.
