Kindle2 specifically. Arrived about an hour ago. I had sample book already ready to go, "House of Sand and Fog" and it downloaded immediately.
I'd already downloaded to my computer a separate sample "A-Few-Short-Notes-on-Tropical-Butterflies" which I proceeded to purchase and download to my computer. I've been able to transfer that book to the kindle as well as doing a few other things with it
I think the only thing I've not yet tested is copying a non-drm mobi book to the kindle. I do expect that to work... I saw some dictionary look-ups working
I do like the display and the size (thin-ness) of the kindle! The ergonomics of button pushing etc are fine, but certainly not what I'd call perfect.
I had thought it would have a Standard mini USB plug but it appears to be propitiatory (like the amazon book format) .
I'd like to thank everyone for their help as I was evaluating whether to take this step to an additional reader or not. I'm a happy guy at this point.
