I have only used Mac's. I have an aging 2010 MacBook Pro and I'm looking to upgrade. I want to switch to a Dell XPS 15 but I'm still not convinced. I'm used to the Mac OS operating system and I can navigate through all of the settings and trouble shoot issues quite well. When I tried the Dell I was quite confused by the Windows operating system. It would be a steep learning curve for me. Also, I'm an amateur photographer and graphic designer and I don't like the idea of using dongles and I don't like the TouchBar on the new Macs either. I keep wondering too if Apple will ever make a touch screen. I tried the Microsoft Surface Studio and I loved it. I'm not hating on Apple nor on P.C.'s. I'm just genuinely confused and I just don't know what to do and it's the reason why I'm still stuck with my 2010 MacBook. I'm also thinking about getting a desktop computer for the first time in my life. I don't know if I should have all my tech in the Apple ecosystem. Any thoughts?
