Gizmodo article

Gizmodo has an article by Brian Lam that has some assertions about E-Ink displays. He writes:
"E-ink is superior for replicating paper, but it can't even support realtime cursor, movements or button presses, let alone video"
Realtime cursor generally just means functionality as shown here: a) rgbpaint running on top of full X11 stack (kdrive/Xfbdev, gtk, etc) on a PXA255 GPIO driven display or b) sketch on same hardware but custom app written by E-Ink engineers to talk directly to hardware from Linux userspace bitbanging gpio. So E-Ink displays can support realtime cursor movements and button presses. His point about video is somewhat true if you want true 60Hz full image quality video, but you can get watchable video with some tradeoffs by using waveforms that reduce update time by trading off image quality. In Portland, I showed a demo of youtube running on an E-Ink display. I only got about 4-8 Hz (depending on video content) because of software and bitbanged GPIO limitations.
