I own a Kindle 1 and just ordered the Kindle 2 yesterday..I paused very slightly about the non user-replaceable battery but took the plunge anyway. One of my Ipods is over 3 years old, and still works. I have other gadgets with non user replaceable batteries that work still also. So, this may be overly optimistic of me, but I figure the Kindle 2's battery should hang in there for at least a couple of years. By which time, they'll have come out with the Kindle 3, which I'll have to have

. I know, it's an illness.
The lack of the SD card option does not bother me at all...haven't used it yet in my Kindle 1. I read all the time, and have many books on my Kindle...still have tons of storage left. I don't listen to MP3's on my Kindle either.
I upgraded because I like the form, and I'm one of those jittery types that was always hitting the "next page" button.

. Plus as I mentioned previously, I'm bad about wanting the next thing. I've tried to overcome this, but no dice. Thank God, I have a secure job that pays well(RN) so I can feed my gadget habit!
I'll end up selling my Kindle 1..one of my relatives always wanted a Kindle but she doesn't like to pay full price for stuff. I bet she'll want to buy it. If not, I guess there's Ebay.
