Small Form Factor...like those made by Shuttle.
No experience with the laptop but every review I've read lauded it with praise - including the battery life which is supposed to be amazing for a high-end gaming laptop. And now, its available with Core 2 Duo processors. And no, the laptop won't be worthless when the DX10 cards come out. Reason?
You'd be hard-pressed to find any half-decent rumor/speculation about their arrival. We have ATi and nVidia launching refreshes this September/October...and there is talk of Vista releasing on January 30. Most guesstimates had DX10 cards pitched for a Xmas release - now, it might get pushed to coincide with the Vista launch.
And if you've noticed, it takes a considerable amount of time for both ATi/nVidia to launch Mobile-versions of their latest GPUs. A next-gen mobile-GPU will be much further off than the already far-off DX10 desktop-GPUs.
