To be honest this one looks like a really cool design too.

(More for actual "Lap"top use,) Then again, the first one I mentioned is built such that you can actually fold your screen down (you know, close the screen down to the keyboard), and fit it in the space behind the cooler and use it as a carry-on/mobile package (comes with a strap).
(1)st one I mentioned is more mobile, but this one seems to provide a good combination of a cooling pad & a "desk" for using the notebook on, has supposedly 4-5 positions for use. Intrigues me a bit, but I'll probably end up going with the first to cool down my GPU & CPU, 720QM is running at 60 Celsius while playing StarCraft II or Crysis, whereas the GPU capped at 78 Celsius (Crysis) (I have a GTX 460M now, remember). (800x600 @ High Settings). I'd definitely feel better if I could shave a few degrees off that temperature.
Anyway, thanks to complication for making such a coincidentally timed post, this was something I'd been thinking about off/on in the back of my head for a while!
