I was considering either it or the Sony reader. Haven't tried them yet though.
It would have a lot less eye strain than an LCD apparently. That would be the selling point for me as I read a lot of items on the computer. I also read on my cell phone, but the battery life would be better here, and again, the eye strain less.
The big advantage of the Kindle is the wireless access. But I really wouldn't use that much as I mostly read free items in the public domain.
