Former Windows phone User
Im very glad Cortana has been ported over - its one of the main things I miss about Windows phone. Its functionality is somewhat limited as compared to on Windows but I knew that going in. Its not tracking my packages (but my Google app is), so some work needs to be done there, but all in all Im pleased with the potential of the app, paired with my Windows 10 pc.
