Considering Microsoft has always had a back door for the NSA, yes you should absolutely Run LINUX, I have been running Ubuntu for a couple years, and will never go back to Winblows. Running Virtual Box for the 1 winblows program I need. All else is LINUX and I have never had any Problems at all. I will say that the learning curve can be rather steep at times, but in the end it is the way to go. The first thing I do with ALL store bought puters is to reformat and install Linux, you should too, especially since it is FREE and Superior
I work for a major three letter computer firm and currently run Linux (Fedora 12) with an occasional load of Virtualbox for MS Project and Visio. Everything else I do is done in Linux and Open Office (Symphony) I have more problems with the virtual windows environment that the entire OS for Fedora.
Running Windows 7. Love it. Very smooth, Apple( ish ).
