I fucking love this thing so far.
Bought a mixed book of poems, loaded up some stuff from Gutenberg via Calibre (NECESSARY:
http://calibre-ebook.com/), bought the paper (which I get free in the office, but whatever), and today I loaded up a few docs I had to read for work as PDFs (update your kindle, folks -- it comes with 2.3 software, and 2.5 lets you read PDFs) and finished them up on my lunch break. Really much nicer than dealing with a stack of papers or a phone.
