way out of abusive relationship?
Well OK, this is admittedly long way off. However, provided new applications are written for "Universal Windows Platform" and thus dependant on Chakra, and also that a new OS project, or a version of Wine, emerges re-implementing necessary infrastructure with help of open-sourced Chakra but on different platform (BSD, Linux), would that possibly help current Windows users to migrate to a new platform, while keeping their Universal Apps running?
It is one thing to buy into platform with no way out, but if you can run the applications you need on a multitude of platforms, some of them open source, that IMO is brilliant. Could be a boost to Universal Apps on Windows, too. Or, most likely, I'm way too optimistic about possible outcome of this move.
