I pretty much agree with the crowd. eInk while fine for now, IMO has a definite "shelf life" and the digital clock is ticking. Tech advancements are happening so fast I am totally with Zetmolm on this.
That link is cool, but like someone commented, you still have the issue of backlighting to contend with, among others. So I kinda think that a major leap forward in eInk tech is less likely than one for the more visually compelling LCD camp.
But ya never know right? Ain't tech great?
