Ubuntu is not that hard. Everything can easily be installed through the software centre or via the terminal, it is up to you. As with all new operating system you need to get used to how they work. After x amount of years using Windows, anything else will feel a bit alien, but the more you use Ubuntu or OSX the more you will grow to like it and in some cases never want to go back to Windows again.
Remember in Ubuntu you can always install Virtualbox and run Windows in a Virtual machine.
I don't know what they have on Mac, but again you can install Windows in it.
What did my head in was that I couldn't use spotify or FM12 (god I'm tragic) Everything else that I could make work was fast
