I own the small kindle and LOVE it. I never thought I would say that. I enjoy books and have always been a "page turner."
***The kindle is light. My arms used to ache after reading a particularly large tome!
***You can finish a book and have it's sequel in a few seconds! Excellent when you're reading a series.
***You can adjust the print size from small to large.
***When you travel you don't have to pack a lot of books since you can get a new book just about anywhere with the 3G wireless.
I had out first kindle and got tired of sharing with my husband so he got his own kindle for his birthday. There is no problem with sharing books between the two household kindles. I hope we can figure out how to share with my sister and niece now.
