Amazon has clarified it's policy on its App store:

• Developers can opt-into DRM
• It's a one time activation

My take? It still sucks.

The problem is that the promises of 'lesser piracy' will be an easy sell for developers, but will tie users into Amazon.com in order to install their applications. Should anything happen (eg. Amazon goes under, or decides not to have an app store), your purchased app could quickly become a useless binary. Due to the volatility of the market, I don't know if this is such a good thing.

Then again, how many apps that I purchased in the 1980s do I still use? Still it may be nice to revisit some of them with an Android emulator in the late 2030s -- which may not be possible with this model of distribution.

I'm torn....
