I used Dos/Windows since Win3.1 up to Windows 7. I am in IT and since XP there is not only the versions but Activation. Change one piece of hardware and then you need to activate again, and not always the easy way over the internet, but your have to call in. The same with Office. Oh the frustration. Then the first thing you have to do is install antivirus software that takes over your computer.
Then 2 years ago I tried Linux (Ubuntu). Nice being free but a pain to manage and install or configure certain software, I can only imagine what it must be like for someone with no IT background. Used this for a year.
Then I read about someone who got Mac OS to run on his PC (Hackintosh). So I tried it, took a few days to get it sorted, but I was so impressed that I went and bought a 5 user license, Only one version, and it does everything.
Damn! What an experience, this is how it should be. Smooth and fast.
It's a pity that this is not supported on all hardware so that everyone can have a real choice instead of Microsoft shoveling crap down our throats every couple of years.
Since then I bought each of my kids iPod touches, myself an iPhone, my wife and myself iPads 2's, she's ordered an iPhone and an apple TV. And also countless apps. I will soon be getting myself a Macbook Air as well.
I think I have left Microsoft behind for good, I have given them enough chances. Even flashed my son's windows phone and put android on it.
