I don't know if there are any other geeks out there. Everyone knows how insecure windows is, viruses, spyware, government back doors (yes its true). It is a cess pit, and I don't trust it to do online banking etc.
So I switched to linux a long time ago. Ubuntu has been my favorite brand, until now. Mint is based off of ubuntu, but has all the nifty things which ubuntu cannot include do to ethical/legal reasons. All the things like Flash, adobe PDF, Java, Mp3/divx/Quicktime/Real support, etc... etc.. etc..
it is gorgeous, and quicker than XP, also it runs tons of windows software using an emulator:
ElderScolls4 Oblivion, Diablo2, Everquest, World Of Warcraft, Lots of FPS too.
Each year it keeps getting better.
Give it a shot sometime if your bored! Message me for support if you need it!!!
