Oh, nothing in particular, I guess. I dabble a lot--in C++, Haskell, Ruby, Java, etc. I really liked using package managers on Linux. I remember using Homebrew on OS X. Is that still around?<p>As for the little things that add up, let&#x27;s see:<p>- Much of it&#x27;s hardware-related, and it might just be due to my poor PC-building skills. For example, my case has a fan that buzzes intermittently, and the ports in back aren&#x27;t perfectly aligned.<p>- Windows isn&#x27;t UNIX-based. I&#x27;m aware of things like Cygwin that emulate a UNIX environment, but it feels tacked on. Also, Windows 10 is nice, but it&#x27;s kind of ugly, among other things.<p>- On Linux, X has given me a lot of trouble, and though Wayland looks nice, it seems like it&#x27;ll be a while before it&#x27;s widely adopted and fully supported. I had a problem with GNOME 3 where it took about a minute before it showed the desktop after logging in, for example. Audio was a pain to deal with, it had Wi-fi connection issues, etc. Also, Linux lacks support for a lot of big applications that I use or intend to use (Photoshop, DAWs, etc.).<p>- Non-English language input is poor in both operating systems (could just be the language I used though). If I recall correctly, OS X had pretty nice language input support, and the option-characters (e.g. Option + E for an acute accent) were really nice and intuitive.
