I just finished installing Mint on my Sony Vaio. I was just tired of having to deal with malware and having to reinstall Windows 7 once a month.
I've only had a few hiccups while working with Mint. My screen turns black when I close the lid and doesn't seem to wake up. And I am having a difficult time understanding how to install software. In particular Jdownloader. But I'm sure I will figure it out eventually.
