Point of clarification please: I'm aware the VRAM has been doubled to 128MB from 64MB, but are you saying that the clock speed of the Mobility 9700 GPU was increased as well when you say "bumped speed of the VRAM"? Or did you mean to refer to the faster DDR2 RAM adn typed VRAM by mistake? I haven't heard anything about bumped VRAM speed given the GPU is still the same, so I'm curious if this is new info or just a misunderstanding.
My Apple Store (Newark, DE) now has the new PBs and iMacs on display, since Tuesday apparently. No PMs yet though. Looking at the display of the new PB, I wasn't impressed by the brightness, although I suspect that the bright flourescent lighting makes all the laptop displays look kind of washed out. I probably wouldn't appreciate the brightness until I got one of them into a more natural lighting environment. Incidentally, it bothers me that the Apple people always have the trackpad speed set to the slowest setting on every machine--it makes them seem slower to potential switchers. I usually bump the trackspeed up quite a bit when I'm in there.
I also noticed in System Profiler that the Superdrive and hard drive now share a single ATA bus instead of occupying separate ATA buses. Any thoughts how that might impact performance?
