Will be interesting if this will be similar to linux with the possibility of community driven repositories alongside official repo's. Or if it's more of an admintool to do windows updates/windows store installs.
It says it uses the same package format at Chocolatey and you can even add their repos. I don't know if there's any caveats to this, but it's a very, very good sign. I am excited about this.
Edit: Apparently, it's also open source [1]
