The Que is coming out soon and has the same size screen--and it's a touch screen--but it's much more expensive.

Also the Skiff reader coming out sometime, and it has a bigger screen I believe (just google it).
And if you don't need e-ink, you have the iPad and all the other tablet devices coming in the near future. Those are more my interest as I want fast page turns for flipping through PDFs, and would rather have it due more than just read and also have internet, e-mail, video etc.
