Now I realize you didn't specifically mention H.264, but still: the VRAM is more than enough to handle 1920x1080 (the full HD resolution -- which btw the screen wouldn't even display anyway).
Yeah, but I see them changing that. It'll probably come with 512 in the fixed slot, then options for 1 GB, 1.5 GB or 2.5 GB total.

Yeah, that's a good point.
I would hope that a GPU upgrade to the next Powerbooks would feature hardware H.264, but the new iMac's GPU doesn't even feature it.
