The limitation is not the TB chip. Eagle Ridge (the TB chip in MBA) is still good for 20Gb/s (two 10Gb/s channels) and one 2560x1440 monitor requires less than 9Gb/s of bandwidth. The issue lies in the fact that Intel HD 3000 supports only two monitors.
hm, does that mean you can STILL do dual monitor as long as the laptop screen is closed?
I cant recall where I read this but the answer is no, the MBA supports but a single external monitor.hm, does that mean you can STILL do dual monitor as long as the laptop screen is closed?
There is a way to have 2 external monitors with the MBA. You plug one monitor in the TB/MD port, and use a USB-to-DVI adapter for the other monitor. It works well, and I use one daily. Many companies make them, based on DisplayLink technology. Currently, the generic driver for Lion is in beta and there are small performance issues using it. It still works well though. But if you are on Snow Leopard, it works great.

We are working on a external graphics card solution that would allow you to use upto six monitors per dock by way of thunderbolt. Others are two but most companies like vidock overcharge you for junk with no support.

The "we" is the design division for a company I own. There is no website for this project because we are still working on development. Unlike others we don't brag or lie about products before we have it going into production. I hate these companies that go to CES and other shows and get you excited about something that never comes to market.
Example. Where are all these magical thunderbolt accessories? So far have little available and everything out is crazy expensive. But we were promised they would be months ago. I do not do business that way. I will update the forum as get closer.
