I think the Co2 savings depend entirely on how much one is using the device.
I have used my PRS to read 3 books in the past month, but the 2 months before that, I had read nothing.
I guess there's a big difference between those reading 2+ books per week, and those reading 3 books the first 3 months, and then perhaps 2 books per year (which is the majority of users I think).
On another note, my PRS-505 starts getting a grey screen. Background isn't as white anymore as it was upon purchase in beginning 2008. Any one have the same issues?
