If you know anything about the Kindle, then you probably know that Kindle format and Mobipocket format are effectively the same file.They're not similar; they're identical (aside from the DRM and a couple new tags).
You might also know that the Kindle itself runs on Java code, a good part of which was copied from Mobipocket. In other words, the Kindle has code in common with the reading app on the Irex Iliad and the Cybook Gen3.
This past weekend I discovered that K4PC has code copied from the old Mobipocket Desktop. This was Mobipocket's flagship app, and it provided ebook conversion as well as ereader management. It was a great app, and it still has 10 times the features of K4PC.
I know one app has code copied from the other because of the undocumented feature. I had found it before in MobiDesktop. It's a feature that only worked in MobiDesktop, and it never really worked all that well. Also, there's no way this was invented twice; there was no reason to add a feature to K4PC that doesn't work on the Kindle.
Neat, isn't it?
I'll cover the implications of the copied code another time.
P.S. If you like this feature, maybe you could send the ebook to fellow Kindle owners.
