It might sound pedantic, but how can you embrace a computer system philosophy?
Surely the way that you use a computer is built from the ground up, using the knowledge that you have gained since first turning a computer on.
I've gone through Windows 98 - Xp - Vista and various Linux installations and business systems and taken something from each one them to arrive at the way I use a computer now, which is comprised of the knowledge that I have taken from the use of each system.
First coming to Mac only a short time ago I enjoyed exploring Snow Leopard, having installed Lion I'm really impressed and enjoying the system as well as looking forward to new developments as Apple moves the Mac experience forward.
However, I'd consider a computer 'philosophy' to be a blend of the knowledge gained by an individual by the use of various systems over a period of time, rather than an idea presented for adoption by a company.
Take a little of all that you know and choose what works for you.
That is the philosophy of the individual.
