After looking at the video...
....I'm sure glad I got an iPad.
Everyone now-a-days thinks that their devices are going to change the way we interact with the world and revolutionise computing. This looks like a great big FAIL.
Too much going on, too many slidey panels, too much stuff that wants to constantly update itself. Looks like it may be halfway useful in a work environment but not quite.
What I love about the iPad is it's simplicity and the fact that it's impossible for me to do any serious work on it. It's for sitting on the sofa, surfing the net and playing crappy games while watching the TV. Tablets will never be anything more than that.
