Me, I'm a whatever-works kind of guy. I use Linux Mint for day to day online computer stuff because trusting my credit card to a windows computer that just might have the latest virus gives me the collywobbles. I use Windows for music making because I can't give up my VST and VSTi, and Reaper (digital audio workstation) is far better than Ardour. I recommend a Mac for anyone (who can afford it) who doesn't want to have to learn about a computer in order to use it, because Macs just plain work... they are severely limited in operation scope but for basic end-users they just plain work. Or at least they used to... Mac quality has been going downhill lately.
One neat thing about my Linux Mint, I have it installed on a flash drive. Modern computers can boot from a bootable flash drive instead of the internal hard drive. Whatever computer I stick the flash drive in and boot, it's automatically my computer - my programs, my settings, my files, my system all on a flash drive. All I need is a random computer to run it.
The downside of Linux is someone is always changing something, and sometimes it might break something. But they'll usually fix it the next day.
"Being a Linux user is like living in a house full of architects and carpenters. Every morning when you wake up there's something new. Maybe a new window in that wall or a new turret on that corner... or someone may have temporarily removed the floor from beneath your bed."
"Being a Mac user is like living in a house that the carpenters never answer calls from. If you need a new window or turret somewhere, good luck. You can't even build one yourself because the architects have it locked down legally. You're just glad the floor beneath your bed is still stable, because you know if it ever gave way it would take five years to fix it."
"Being a Windows user is like living in a cheap Vegas motel. Every morning you wake up with new bug bites and a new disease. The floor beneath your bed is continually in danger of falling through but you take comfort in the knowledge you could always move to a different motel room, or burn down the whole thing and build a new one fairly easily."
