Now, this might be a very stupid question, but:
If what Hellhammer says "Thunderbolt is essentially just PCIe port" is true, then we could see EXTERNAL graphic cards in the future? So you would have an MBA with crappy IGP, a thunderbolt connection to a graphics card in a separate housing, and then a thunderbolt connection to your ACD 27"?
If that's possible, I think the market could be quite big for such external graphics cards, no? Not as popular as external drives, but still something that would be bought by quite a few.
Does anybody think, we'll see such cards within the next year?
more like two to three years.

the echo express is the unit and it comes out this year near the bottom of the link page. I think the issue of 1 t-bolt not giving a good enough bandwidth for a good gpu card will be solved in two or three years. one way is making a Mac with 3 or more t-bolt ports or making your airbook with all t-bolt ports. then you could use two connections to the echo express.. Also if they make these light based the bandwidth will be greater.
This would sell big with mac mini's and may finally allow good gaming on all macs.
