The E Ink Carta is the electronic paper display used in the Amazon Kindle Voyage and latest generation Kindle Paperwhite ebook readers. It has 300ppi resolution, a very good contrast ratio and excellent readability even in direct sunlight.

The current Kindle lineup includes only readers with 6" displays, which many people find too small for comfortable reading. While larger ebook readers exist on the market (such as Amazon's own Kindle DX), none of them seem to have a display as good as the E Ink Carta in terms of resolution and contrast.

Interestingly, the Carta product data sheet states that sizes up to 13.3" are available from E Ink to manufacturers. Which end-user products contain those larger Carta displays? In particular, are there any ebook readers (current or planned) with a Carta display larger than 6"?

I have not pulled the trigger on this purchase, (because of the relatively high price), so this is not a hands-on recommendation. When I went looking for an e-reader for reviewing and consuming technical information, I was most tempted by the Icarus Excel.

It is a 9.7" reader and allows for handwritten notes too. Since I was evaluating for technical learning, this was a big plus. The Icarus site is not great, but there is a good review, with video, here.

I don't think the market for these larger format readers is particularly mature, and color e-ink may yet disrupt the entire market (small format included). If the larger format is a must have, and money is not an issue, then the Excel looks like a good option right now.
