After a few emails with Pixel Qi Corporation it seems that the 1280x800 10.1 inch screen version is on schedule to for a Q4 2011 release. Most likely we won't see products with the screen until 2012. My dream tablet project will have to utilize the 1024x600 version for now, but I plan on upgrading eventually.
I'm also requesting a development kit directly from Pixel Qi which should save a few dollars. Maybe I can be lucky and get a 1280x800 prototype.
The Pixel Qi screen uses LVDS. I'm still not sure if I'll need an adapter to make it work along the Fujitsu T580, but we'll find out when all the parts arrive at my place. I have been checking out PChub.com which does have a lot of cable converters (link).
Doesn't this look amazing?
