I have been thinking.. It's quite likely that the next version of the Air will have a Thunderbolt port. With transfer speeds of 10gb/channel it should outperform PCIe (I think at least, I believe those operate at 8 gbit/s, correct me if I'm wrong). Could this mean that we will see external graphics boards for the Air in the future? A dream scenario for me would be using my Air when travelling, for meetings and such, and then when I get back home, docking it to mouse / keyboard / cinema display with an external gfxcard, giving me a much more competitive working station when docked. Could this become a reality in the near future? What do you guys think?
