TLDR; A 'Pro' product isn't defined by some arbitrary nonsense like the number of buttons it has. It's defined by how well it does the job it is set out to do. Use the tool that matches your needs.
If you think the definition of "Pro" requires having a nasa-like control panel to manage the fiddly details of your equipment, then your not a professional... you're a child who only wants to impress his friends.
A professional-level device helps you get your work done with as minimal hassle as possible. A professional-level device is reliable, because the person using it is trying to get *real* work done, and doesn't want to waste time dicking around with inconsequential bullshit like whether the color of your window borders are exactly #FEFEB0, or if you can shut off the wifi using a physical toggle button.
It doesn't matter who makes the device, or . What matters is whether it does the job you need it to do, and that it does so reliably without getting in your way.
I switched to using Macs when I finally got fed up with Windows and it's utter inability to suspend/resume reliably (among other things). I had initially tried to switch to linux, multiple times, but I couldn't find a single distro that could handle suspending properly, not to mention there was no decent virtualization software to run non-linux applications on, and there were no decent alternatives on Linux that compared to stuff like Microsoft Office or Adobe products.
So I moved to using OSX and haven't looked back since. It's the perfect combination (for me) of all possible worlds. Major vendor support, good virtualization tools for when I am in a pinch and am forced to run something windows-based, but I still get all my unixy command-line goodness, etc. And everything for the most part works. I don't have this perpetual worry in the back of my head that I'm going to sit down in front of my computer one morning and my computer is completely fubared because of something I couldn't have anticipated (Like Microsoft botching yet another update).
Game support on Mac is more or less crap compared to Windows, but I'm not a big gamer so I don't really care that much.
