They're not doing that great. A4 (or letter) sized ereaders right now cost $800+, have a resolution of about 200dpi and only a few shades of gray, so they're practically monochrome. For that amount I can print thousands upon thousands of pages at 1200+ dpi on real paper which I prefer. I thought about it and bought a laser printer. When the technology matures a bit more, I'll be waiting. Less eagerly every year though, as I've been waiting for affordable large ereaders for 10+ years now. And I'm seeing a shift to tablet-like device features which I'm not fond of.
