Okay, so Windows sucks (big surprise). What about GNU/Linux? I've been using it for more than 5 years full-time and I've never had any show-stopping problems or problems that couldn't be solved with a 5-minute Google search.
For instance, when I tried Xubuntu, my GPU was running at a constant 90 degrees Celsius for no real reason. Found out it was because it was also rendering another 5 screens in the background. Deleted them, after 3-4 days they would come back. My screen was 1920x1080, but it liked to change my resolution to 1024x768 every 5 or so boots.
Tonnes of small problems, like the "settings" program emptied itself. Then the Windows key would stop bringing up the menu thing. And icons liked to disappear from my desktop.
Then when I tried Debian, I could install it fine, but couldn't boot. Pretty sure this was also to do with the GPU.
Then when I tried Linux Mint, it worked okay for a day, then apparently I didn't have permission to change wireless networks, and I had to plug in a PS2 keyboard to decrypt the volume on boot (though this was easy enough to fix, just had to find the right Logitech USB Keyboard module to put into the initramfs). Again, many small issues that escape me right now.
The only distro that has worked well, with no bugs (that I didn't introduce), was Arch, but Arch is a real mission. Only thing is my wifi speed is slower than it is on Windows/OS X (~600kB/s down from ~1000kB/s, not a huge deal). Arch is great as a project IMO, but if I have to write an email or do banking or something, I really don't want to have to mess around with config files.
I love Linux so much, but that's why I'm currently an OS X user.
