You do realize how terrible the comparison is with LCD/CRT to LCD/eInk right?
CRT's were heavy, power hungry (energy inefficient) and massive objects. A 22" CRT would have been more than 100lbs and around 2 feet deep. A single CRT occupied almost half a standard desk, and consumed about 70 watts of power which was almost entirely converted to heat. (In my experience when the LCD transition happened office spaces often had fluctuating temperature levels because the HVAC systems were designed to compensate for the daily CRT heat load, so after the transition you ended up with rapidly cycling temperatures all day long until they came in and re-tuned it all for the reduced heat load.)
A equivalent 22" LCD is about 7-10lbs, 7 inches deep and uses around 20-30watts of power. On top of those <sarcasm>minor improvements</sarcasm> you also have in general better resolutions, better refresh rates (less eye strain), less heat output, better color reproduction, digital image transfer and about a dozen other improvements over CRTs. In fact about the only area where CRTs were even better than LCDs was the ability to do multiple resolutions (only the best CRTs can still compete) and better blacks.
LCD's displaced CRTs because they were better in almost every aspect, as soon as prices came within reason they began to dominate almost immediately. In my experience everyone wanted LCD's just to get back all the desk space they lost to the CRTs. I can remember all the exclamations on the returned desk space vividly.
I think that comparing the CRT/LCD transition to LCD/eInk isn't even in the same ballpark. Ask an voracious reader that's tried both which they prefer to read on and I've yet to hear a single one say they prefer the LCD. I agree that ultimately most devices will be LCD, but eInk will likely remain around until they develop a technology that matches the advantages of eInk (ultra long battery life, eye strain, weight and price). eInk has serious advantages for a specific market segment and as speculated by others if they get the price down to where the things are damn near disposable you will see them everywhere.
