As we all know Microsoft is an incredible rich. God knows how many people work there and I guess they all get paid very well.
Still they release after release they create an OS which is unstable and insecure.
Majority of Linux as we all know is free leaving RHEL, SUSE, etc and still Linux has become a stable and secure platform.
What do you think is the problem with MS ? They lack ability ? They are lazy ?
One thing I must admit coz its reality is the fact that Win is much more user friendly than any Linux distro. So that credit goes to MS.
