Thanks. If I prefer a wireless controller, is it better to get a Xbox Wireless controller instead? How bad it is without special features (e.g. trackpad, motion sensing) that the ps4 controller offers?
Also, it seems that both Sony and MS offer some kind of wireless adapter for Windows 10. Why we need those adapter given that the controllers have bluetooth?
If you want to have Dualshock's features (such as motion sensing) you will need to get the adapter, Sony provides. Basically, you can use the Dualshock via Bluetooth but all its features will be lost. The adapter works as a "translator" for both the Computer and the Dualshock and you get everything you would be getting if you had a PS4.
If you do not have enough USB ports you can always purchase a USB Hub so that's not really an issue.
Xbox's Controllers are more "native" to the PC as they share very similar features. That means that it will be easier for an Xbox controller to work with a computer rather than a Dualshock.
If I had to choose, I would, without second thoughts, purchase a Dualshock adapter.
