I run Linux Mint on everything but two. Need Windows for my Majic Jack. And for some software that there is no Linux equivalent.
Other wise. It is LM. This LT, My tower upstairs, the LT my brother uses and I have converted several of my friends over to Linux and they hate windows now.
Had another that wanted Linux on her PC but it was dead. Not sure what happened to it but I could not revive the thing to save my soul.
