An Unabashed Geek at that. As much as I like the way Apple looks and feels, I detest that you are locked into it. The same goes for Windoze.
With GNU/Linux you have multiple #Desktops. #Gnome is probably the most popular (but please for Gawd's sakes don't quote me). Then there's #KDE (which makes me think of Windoze). Then #Mate, #Cinnamon, #Budgie, #LXQt, #Deepin. These are just a few. Each has it's own pros and cons (LXQt is extremely light on resources but not very customisable). Deepin has incredible graphics and animations, but is extremely resource hungry. Mate uses Gnome 2 (because the author hated Gnome 3). etc etc etc...
