Of course, the actual Kindle can't play this media, which probably means a few things. One, Amazon realizes how important the Kindle app is to their overall strategy -- even though the iPad is a competitor to their own hardware, Amazon is fine with running both horses in the race, so they have a better chance of grabbing a larger audience. Two, Amazon is most likely working on another version of the Kindle. They probably can't compete with the iPad on quality (given Apple's experience at this point at making and selling beautiful hardware), but they may still aim to compete on price. Which shouldn't bother consumers -- more competition means more choices, and that's always good for us.
