I hated the first gen Kindle for its ugliness (first) and its (personal) uselessness. I'm a collector w/r/t art artifacts. Books. Albums. Videos. Books mostly, so having a book-less medium was anathema. Now, with the trip to Thailand in January, I simply cannot carry the volume of books it will take to make a ~20 hour one-way flight bearable. With the niceification of the Kindle design v3 and the more pressing need, I purchased a Kindle. I still plan on purchasing physical books for each bit book.
First things first, and these first things occurred prior to receiving my Kindle: Project Gutenberg is my hero. Years ago I'd donated money to them on principle.They deserve so much more for what they've been doing for 40 years! A few years back (prolly longer but can't find a ref) I got the itch to read the classics that I'd not read growing up or in college. Years ago I went through a Sherlock Holmes period; I'd picked up at the airport and read with fascination Catcher in the Rye and To Kill a Mockingbird; in college I went through a notable Dostoevsky period, reading most of his works. There're always classics you haven't read, and I'm glad that I can read Voltaire and Oscar Wilde and Jane Austin comfortably and conveniently since they're on PG. This is the impetus of Wikipedia and Project Gutenberg.
Calibre is an absolute must-have, software-wise. Where is the competition? (Maybe FOSS as a system produces one primary solution until demand increases.) Complaints on Kindle/Calibre: still not sure how to use Calibre to group a series and have it grouped on the Kindle in series order. Somewhat minor. Also: no way to find what you're currently reading and/or group by what you've read.
Fourth paragraph that is shorter than the previous. Screen is beautiful and readable.Case is solid and feels good. $140.
