I love, Love, LOVE reading eBooks.

My library has a huge eBook collection of 17,000 eBooks which I can download at 2am for FREE!

I can download an eBook in the middle of a winter storm here and stay nice & warm. I think most of their collection is the current bestsellers or the most popularly read books, not just the public domain snoozers.
For non-fiction, research type books, I can download, skim for the needed info and delete at will. I can go through several books this way without leaving home or having to lug several books home for only 2 chapters worth of necessary info in each book.
For fiction books, I've read a lot of new authors & genres I never would have looked into before. Since I don't have a car, I really have to think over carefully each book I am going to walk home. I hadn't realized how much that limited the choices of books I was willing to risk taking home. Each book had to seem like a sure bet.
I can't tell you how long ago it was that I stepped into my actual library. I still have a $10 library fine to pay off. I returned the books a week late but didn't haven the money pay it off at the time. Since I used to take out about 5 books at once, if I can't make it back to the library on the due date, I wind up paying 25 cents per book for each day overdue, times five. Ouch!
With library eBooks, the book file automatically doesn't open past the due date and I simply delete the file. No more library fines.
The biggest feature I love about eBooks is the ability to change font size. My eyes have gotten worse as I age. Switching to the largest font size has been a god send for me. Also, since I don't have to flip actual pages, I'm reading much faster.
I don't have a Kindle or any other eReading device yet. I download everything to my portable laptop, set up a few pillows and can read in bed or on the couch. I can even read and eat messy foods at the same time.
