Yeah these days if you want a linux laptop you're going to have a better experience either installing linux under bootcamp on a macbook, or getting a laptop with linux pre-installed, or getting a chromebook and running ubuntu under crouton. The dual boot days are basically over. If you have windows often its boot load locked into windows10. You can run bash ubuntu under windows 10 now, but you still have the overhead of running windows10 itself compared to the speed and efficiency of running a linux desktop like xfce.
