J complains that the Mac version of Kindle is not exactly stable:
The Kindle for Mac application is crap. Not in the sense of “limited functionality and poor UI†(although those are true, too), but in a more serious “corrupts user identity every time it does its (weekly?) auto-updateâ€. I had originally thought the problem was with the version available in the Mac App Store (which, thanks to Apple, is much, much older), but no, the direct download from Amazon does it as well.
I’m guessing that Amazon is starting to wean itself from Apple given that there’s the issue of in-app purchasing hanging over their heads. I’m not really sure if there wll even BE a Kindle version in the App Store in two months, esp if Apple sticks to the June 30th deadline for in-app compliance.
Even if Amazon and Apple divorce, iOS/OSX users will eventually be able to use the web-based version of Kindle though. I haven’t used it yet, it’s still in beta, but it should be available soon. At such point I would expect Amazon to dump a lot of dev resources into the web version as well to keep people from jumping ship to ibooks.
