As for the rest of the demo, well -- shrug -- it looks like iOS. I tend to agree with the downvoted grandparent: bring something new to the table, or don't waste my time. My guess is that few people other than patent attorneys will end up making any money from this product.
In any case, if someone at Apple were to load up on Red Bull and pizza and camp out in their office for a weekend, iOS's task-switcher could look and work exactly the same. They apparently believe they're doing it the right way now, though, for whatever reason.
I've gone back and forth between webOS and iOS phones over the past couple years, and while webOS is not better in every way, and is significantly handicapped in some ways, it's also significantly better than iOS in some ways. I really don't see webOS phones as poor attempts to jump on a bandwagon just to scrape whatever profit they can. This is much more a case of healthy competition.
I too expect Apple will eventually adopt a similar multitasking paradigm for iOS (you could call it Exposé-inspired, or webOS-inspired, as you wish), negating webOS's most obvious advantage. Which you could attribute to the effects of competition. Or maybe Apple would have inevitably done it once the hardware got powerful enough -- who knows.
