desertblues - thank you for your encouragement! Just got my Kindle (WiFi) yesterday; it came while I was at work, of course, so I didn't get to look at it until around 8 PM. Charged it up for the night and started playing with it this morning. I had "purchased" a bunch of free books from Amazon; they automatically downloaded to my Kindle once I joined my network. Very cool.
I also had downloaded "The Complete Works of Shakespeare" (.mobi file) from Project Gutenberg to my PC and downloaded this to my Kindle via USB. This choice was a mistake, unfortunately - it was formatted O.K., but there's no table of contents so you can't go to a play or Sonnet or whatever you want, just have to go page by page to find it; needless to say, this was a no starter!

I deleted it and will just download plays separately. Live and learn!
Anyway, I'm presently very pleased with my Kindle and hope to start reading books very soon.
