We have an high tech whiteboard in the office I work.

And it is fine, it is always on, you can draw as soon as you pick the stylo, the UI is minimal to non existent, you just you can drag the screen left or right to get more screen estate and when you are done you can email the result to your inbox. I actually like it.

It is not significantly better than a whiteboard, but also not worse. It is probably 100x more expensive though.

Edit: it might be cheaper than having someone that make sure that working markers are always available which is a common failure mode of phisical whiteboard. How long this will last we will have to see.
