My Kindle books download in a few seconds. And then they are loaded completely and I can jump around in them rather well now. Properly linked books even let me jump from exercises to answers and back rapidly.

And there is some irony that I am likely tracked heavily on what I've read. Certainly on what I note. So it isn't like I'm clamoring for no scripts. Just find it odd that the push for web applications has destroyed the use of web pages.
