Thinks you can get an STD from flirting.
Nah. If you're talking laptops, then yes Macbooks are probably the most popular option (though dwindling). But developers [at least at Google and Nvidia] generally use Linux for coding work, and windows otherwise. Obviously if you're developing for another platform you'll use that one too.
Google and Nvidia is a very small portion of developers as a whole. Almost every professional freelancer will use Mac along with any company serious about developing their own software. Linux as well but that can vary. Windows? For few specific technologies maybe but no chance it would be a popular choice.
