The point about having an hybrid device is that you can use it in different ways, ex. as a laptop when you are doing productive work, or as a tablet when you just want to relax and check social networks or play some games. You don't need to purchase 2 different devices.
The fact that you are using a "pro" device doesn't mean you wouldn't want to use "non-pro" apps, and having a full-featured Android subsystem (which emulates ARM if needed) is a good advantage when you want to use apps that don't exist in the Windows market, or want to use your previous purchases in markets like Amazon or Google Play.
Remember that several companies just focus in releasing iOS and Android apps and fall back to the web version for desptop, which usually is not optimized with a touch-friendly workflow.
