That's so cool to hear. I haven't even had mine that long, and I'm already an admirer. Sound like I'll dig it even more as time passes.
(Note to those on the fence. I'll give you some background info about myself: I'm NOT a big book reader. Pre-Kindle, less than 5 a year. NOT a big gadget person. Software and virtual servers w/too many providers? Yes. But gadgets no (i hate "stuff." Have no printer, a bad, simple cell phone, no dvr, cable box...). I just really like studying and reading, and the Kindle helps a lot with that. I'm not saying, "get a Kindle!!" I'm just saying if you're trying to map your needs + interests to people who have one, those are some things about me...)
