I've used e-textbooks for about 3 years now, and never with any problem. I used them on my laptop (which did cause some eye strain), but all my highlighting tools where there, and a full keyboard meant I could take notes on the fly or copy/paste into a text file. These wouldn't really hold up well on a Kindle unless I had unlimited highlighting capabilities.

The biggest pro: text searching. Nothing beats it when you need to look up a keyword.
The biggest con: page turns. I still can't get used to not being able to flip back a page or two with ease. Something about my method of studying that just doesn't mesh well with ebooks.

My husband just used my K2 last week when he had to read a management style book (not a textbook) for class and do a write-up about it. He found it particularly easy because he could highlight easily. In this case, there was no real reason to take additional notes, so that wasn't an issue. Since we purchased the book from Amazon, he then logged into my account online and was able to just print out all his highlights on a one-page document that he used for easy reference when writing the paper. He was simply stunned by how much easier this made his work.

EDIT to add: the only reason he had to log onto my Amazon account to print out the notes was because I had taken back my Kindle and he was out of town on business and had some down time. Otherwise he could have just accessed the Clippings file on the device itself. In this instance, buying from Amazon worked to our advantage.
