Mostly just posting to get rid of that annoying message that I haven't posted yet.
I don't have an eInk device yet, but plan to have the Kindle 2 (not DX) within the next two weeks (birthday present!). Once I get it, I will likely install the custom screensaver and PDF hacks - assuming they both work with the latest firmware.
Anyway, I plan to spend a lot of time on these forums to learn more about my Kindle.
