HP released a video showing more of their Slate computer. It's presented entirely by someone from the Adobe Flash platform team interestingly enough.
So the key bit of new information from this video seems to be the Air application HP are using for an application launcher. I don't think that's been mentioned before, but it isn't that big news really. Like their multi-touch desktops they always have a specific front-end on them. I just hope they give the Slate 2GB of RAM.
The main point of the video essentially seems to be a long stab at what the iPad can't do. It mentions statistics like 85% of the top 100 websites use Flash, 75% of all video uses Flash. In addition Adobe estimate more than 70% of all casual games on the web are written in Flash. And obviously to anybody following along, none of that will work on the iPad.
It's good they're trying to communicate these facts, back when the iPad was announced the only thing media could say was how amazing it is, while quoting Steve Jobs saying it'll provide the best browsing experience on the planet - something a bit difficult to argue considering it doesn't support Flash. Obviously nobody from Apple plays games on Facebook, or Portal Forums so it seems.
