The table responded just as you'd expect to chucking photos around and resizing, rotating them but I really can't see the appeal. I'd much rather look at a very high resolution screen or picture frame when displaying photos rather than look down at a lower resolution table (only 1024x768 pixels!). For games however, If they can bring the price down on these to below £1000 then these could easily compete with or replace board games and group/party orientated consoles like the Nintendo Wii.
Here's a photo of the surface in action (In use by the two people who were standing next to me).
Unfortunately the frame rate then dropped and the movements got a little jerky until finally the application crashed!
Back to the positives though, this table will be really good when it's cheaper and I can't wait to see the applications people develope for it.
