First, that is my favorite reply all day. Freakin' hilarious "..last known living photograph..."
Second, one doesn't just have a prototype tablet made to show around. Especially one that is so thin and polished (the overall tablet, not the glossy finish). It takes untold months of work and loads of cash. Why would NVIDIA expend such resources to show off their secondary chipsets, etc? This has to be a product headed for the market. Now, that said, I will be shocked if it is from Apple (see above quote from TheSlush).
Reports just in Jen has accidentally fallen out of a 19th story building and under a cement truck with his prototype, his remains have disappeared down a drain and out to sea.......... and eaten by seagulls nothing remains....
