I wrote about my first e-text experience recently for Teleread:

The short version: it was a complete disaster, could not do anything with it but read it off the computer screen, or print the whole thing. No way to save it electronically for future reference, no way to even cut one sentence to cite in a paper. I had to retype individual words and phrases by juggling back and forth from two browser windows. Fail!
