Well, it's still early, so we won't know yet how friendly, robust / stable and compatible it will be. I expect not every program will work regardless of whether you have installed the right version of the libraries or not. In the tests they are doing they say VLC for example is not starting up.

I also think that the stats showing it running better than Wine might be a bit premature too.. it's not impossible for the performance to get worse when more gets implemented in order to have wider support. But we'll see, maybe it does result in a better approach.
