I use a Macbook Pro 15" as my daily driver. As a college student it is great for much of what I need in classes, typing documents, reading assignment and web browsing. The trackpad is great, battery rocks, and it does the basic things without any fuss. Additionally the Apple store 10 minutes down the street handles any issues should they ever come up (just because engineering students likely CAN fix their own computers, doesn't mean it isn't advantageous to be able to hand it over and not stress about it sometimes). Fully loaded it handles pretty much everything I throw at it, no problem. As an iPhone user it also comes along with the benefit of having my text messages sync up, photos sync, all that jazz, built in with no fuss.
I dual boot the Mac with Windows 10 and use parallels to have a VM of the windows partition. This is mainly for CAD but also serves to grant me access to a handful of other window sonly programs. The VM is nice for "I just need to swing into SolidWorks and grab a few screenshots" while booting into Windows is nice for "I'm going to sit down and do some CAD for 3 hours and want the performance"
All in all I am pretty happy with it as a daily. That being said I also use a dedicated CAD desktop running windows for when I really mean business
I have found that a machine running windows that is used just for CAD and a web browser is pretty nice, many of the cons I would come up with for windows don't occur until it has been bogged down with a million things (antivirus that gives you a pop up daily telling you things are going great, a million programs requesting updates.....)
For me Mac OS is nice because it is just seamless, no annoying messages, most things happen automatically rather than requiring permission and popping up windows with alerts, the basic things work well and work out of sight and for me that is worth something. As a college student who doesn't want my computer to be something I have to think about, a mac has served me well.
I always find the Mac/Windows or iPhone/Android arguments interesting. To me neither one is BETTER, each just serves a different user. My mother loves her iPhone because when she needs help with it her friends have iPhones and can help her. My roommate likes to fiddle with every setting possible, write apps, and play around with every single feature of his phone he can, and he loves his android.
