I just bought this Brooklyn Dodger book from the Kindle Store, changed the suffix to .prc and it works great on my Iliad...no drm!!

Anyone else have a list of drm-free Kindle books?
I didn't expect this one to be drm-free---and would be much more likely to buy more if I knew before buying that it would work on other devices.
