Here's a neat video from Apple in 1995 which, among other things, shows a couple of tablet devices. These devices would not have been able to be created with the level of performance shown in the videos at that time obviously. But I did find the video inspiring and would love to see some visionary concept work for enabling education through technology done today.

We'll see where the event tomorrow takes this, but I don't think we'll be seeing something as revelational as this video would have been in 1995.
