(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...)
That said, I "bought in" intellectually accepting that I shouldn't expect to straight up enjoy all my PDF's on this thing. I decided e-readers would be something that would be worth it (for me) to take a hit with the early adopter tax.
I'm generally not a hardware fanboy, but the Kindle is to me as guns are to the NRA: if you want to separate me from it you had better be prepared to pry it from my cold, dead hands.
