> The e-Ink people have got to get their costs down.

I work in the display industry. No vendor can get their cost down unless they're able to get their volumes up to millions of units per quarter. It's a power scaling law. I doubt E-Ink even manages to sell 10,000 32 inch displays per quarter and if I'm not mistaken these backplanes and laminate material are kerfed by hand! Notice that small sized displays on the other hand are much cheaper. As long as there's nobody willing to pony up an order for a million 32 inch displays, the status quo will likely remain the same.
