I've been a die-hard Mac user for 10 years and was "forced" to try Windows when a software a needed wasn't available for Mac.
I found out that PC's are not as bad at all as Mac users would think. After a year or two I actually sold my very expensive Mac setups and never looked back. Our business still needed a few Macs for clients demanding them (so I was in the loop about how things are done on the Mac), but generally speaking I was more and more disappointed where Macs were goings. A lot of things were much more clunky and not-straight forward. Especially the OS! I think the spirit of simplicity and user-friendliness got lost over the years. It's all about looks and image now! ;-)
Windows 10 is great, and so was Win7. The thing with Windows is that it's up to the user to choose the right hard and software. If you go for quality and choose wisely, you have an amazing setup.
Just a few banal examples (but that kind of though-line goes for many many things): On a PC I can connect my iPhone or camera and see all the files in the Explorer to browse. You try that on a Mac! There is nothing in the finder. It drives me nuts!
And why the hell do you have to un-mount/eject a USB stick on a Mac in 2016?
Which idiot places the power switch for a Mac Mini at the back? This is something I need all the time and you have to fumble blindly for it. (I have one for my TV next to my Sat box under the TV and you can imagine how inconvenient it is to crawl at the floor trying to reach the back with all the cables there or not to mention to get a USB stick in at the back!! Why the hell is this not on the front?
I remember when Macs had a power switch on the keyboard! That was the 90's and this was when Macs truly were light years ahead of any PC. Music and graphic design could only be done on Macs.
These days there is nothing I really need a Mac for. It "looks" great, but if you try a bit, you can make a windows machine look great too. I use a Asus Zenbook as my laptop and it's as good if not better than any Mac laptop.
But in the end, the differences are really small. I would stick with what you are used to. You will spend a lot of time to adapt to the new environment and you really have to ask yourself if all the pain is worth it! You can make both environments work these days. And the lame excuse that graphic design is for Mac only is not true at all. I do a lot of graphic design myself and there is nothing I can't do on PCs. People even do most video editing on PCs now (also something that you could only do on Mac for a long time). In fact there are a few things I wouldn't be able to do on the Mac! The "Mac myth" is just by-product of all the graphic designers that had Macs in the 90s and most of these businesses still run an all Mac environment, because that's what they know/have. Again, why would they switch? There is no reason. but if you begin your "coding-journey", you can't go wrong with either.
What I like about Mac is the fact that there is not so much to choose from (in terms of hardware) and if you have enough $ and not much time to research, you can't go really wrong. On the other hand, I can customize my PC (especially my desktop) much better to my needs. Everything I have from the keyboard to the monitor to the motherboard, chassis, storage etc. is exactly what I want and usually better what a Mac could offer me.
