Gamer maybe interested, I didn't know this existed, seems pretty interesting.
It looks like you can take a laptop and put a desktop graphics card with this device / dock. A bit of hack but look at the youtube video below doesn't seems too hard. The video shows mini-pci version, but this product link is for express card version. $36 gives your laptop option to play high graphics game is not bad. Say you are traveling, bring your laptop, this device and your expensive graphics card, you could play your fav game on a hotel TV
EDIT: You don't need the express card or the mini-pci connector if you are displaying it to external monitor / TV.
EDIT2: Oops sorry, I think I'm wrong, I think you do need the either express card or the mini-pci connector on 2nd thought. Dumb me, how else can the laptop display. Yea, then it gets to be messy, probably not worth the trouble unless you don't mind.
