Tough demands here lol!
The thing is, Blu-ray and HDMI output still costs quite a lot. Also, anything like a GTX 260 mobile will cost even more. And having both of those pretty much necessitates a fast processor to keep up. And by then, its pretty much impossible to get good battery life or a price tag around a grand.
If you're looking for a value gaming/multimedia desktop replacement, those are just some drawbacks. But the best manufacturers for those kinds of notebooks are still Asus, maybe Toshiba, and of course, the expensive Alienware.
