I wonder what the Window's Kindle PID will be. If it is the same as the Windows MobiPocket PID, or is otherwise discoverable, this will provide a way for almost everyone to get access to the Kindle Store's AZW ebooks, strip the DRM (if any, a small but significant percentage of AZWs don't have DRM), and read the resulting DRM-free MOBIs on any device. Note that stripping DRM from ebooks you bought for personal non-commercial use isn't legal everywhere, see a recent
post by Xenophon on the murky situation in the US.
