Chipping in my 2 cents, I went from Vista to Linux totally. I'm currently using Debian 7.5 but before that I was using Ubuntu. I will never go back to Windoze. I only run XP pro to sync my iPod and thats it. I installed Debian as the main OS and installed Oracle Virtual Box then installed XP as a virtual machine. There's a great reduction in virus and malware threats (but not completely). Yeah, I made the right move to switch to Linux. SO much free software that is useful and my laptop is not being run to death as Vista did.
