More like 40 years now! I have said ti for a very long time, Microsoft didn't innovate in technology, it innovated in sleazy business practices disguised as technology.

It is difficult to find some of the more awful practices nowadays but I was always amazed at just how far they would go, and a little impressed by the thinking, to undermine all opposition.

Microsoft is like an Alpaca, if they start getting friendly towards you, it means they are about to attack!
