Sorry, as one that uses Linux to death, Windows when forced and all...
I'll stick with my MacBook Pro, due to its hardware capabilities.
*Each* OS has its strengths and weaknesses, depending upon usage.
Windows is, essentially, king, due to ease of use/misuse by the average village idiot and regrettably, all to often maintained by other village idiots.
*BSD is nice, but it is a lot stodgy in admitting to new interfaces/technology. As in taking two years to admit a beta USB system and three years to get the damned thing to actually work properly.
Linux is nice, if you like rough edges. I use it daily at home and frequently at work.
Linux is nice, but it's unpolished in may areas, when compared on a desktop level with Windows or OS X.
From that standpoint, I've eliminated all Windows desktops at home. I still maintain a Windows server, due to certain commonalities issues.
All desktops are Linux, my singular exception is this MacBook Pro, where I am typing from now.
Now, from a security standpoint, I condemn all.
Linux for partially adopting SELinux, *BSD for not bothering to seek NSA input in a far more merciful time, Microsoft was totally out of that program. Said program was to teach how to build a Trusted Operating System.
Still leaving Solaris, in certain special configurations, as the *only* trusted operating system for the US.
