List of things I want in an OS:
1. Unix-like, the stability and safety of Unix is and will forever be better than anything Microsoft churns out, bar none.
2. Compatibility with Adobe Suite
These two things alone narrowed me to MacOS, especially after trying to use Windows 10 and being so disgusted with it.
And a little background: I used to use nothing but Dells, because they always gave great deals, and I always optioned out a machine that would be better spec'd and for less money than an equivalent MacBook Pro. I thought I was getting a deal, and being able to play games was a bonus! I was they typical "Macs are overpriced garbage for hipsters" guy.
And then after 3 years the laptop croaked, every time. Then I talked with the "Mac hipsters" and found out they were still using nearly decades-old Macs.
And then I bought a MacBook Air for an iOS development class, and adored it. This combined with my hatred of Windows 10, and knowing that 7 would eventually EoL, I made the switch. Frankly, MacOS made using the computer less of a pain in the ass. I also bought an iPhone after learning of the compatibility between them, and I can take calls and texts from my computer, seamlessly, and everything I have syncs automatically between my laptop and desktop.
So when I had to buy a laptop for a job/internship in January, I set my sights on the new MacBook Pro, 15", Radeon 455. And while I was weary of all the criticisms, I knew I had a month to return it so I leapt.
And you know what, I loved it too. The trackpad is so good that I don't have to use an external mouse (and kinda miss it on systems I have to use a mouse for), USB-C hasn't bothered me in the least, and I get great battery life, even though I have a lot of programs open all at once. I've even got use out of the TouchBar, enough so that I miss it while on my desktop.
Yeah, I would like to have user-replaceable parts, but going to a Windows-PC to do it would just be so much BS that I don't care to. And since Apple has the fastest SSD's on the market, and some of the best battery life, it doesn't really bother me.
As for the old tech argument, Kaby Lake has what, a few mHz improvement over Skylake? I'm not going to buy a machine solely on spec bench racing, I'm going to buy one that I'm comfortable using, that I don't have to **** with, and actually works with all of my devices.
