Considering you are a 'Computer Engineer' you could give the guy a bit more of an appraisal.
Will this do for the lad, Blas?
Considering all the cockups that were the result of Vista being released without due thought and consideration, none of that has happened with Windows 7.
I never had Vista because of the initial problems and because my XP Pro worked well enough for me.
My only contact with Vista was cleaning up a couple of infected computers and as a sworn XP Man I did not like it even after the flaws by Microsoft were sorted out.
My old XP finally packed in before Christmas (hard drive problem) and I bought a nice Packard Bell kit from PC World. It came with Windows 7 Home Premium and almost as soon as I set it up I liked it very much. So much so that I went and bought (the company, No not really) an OEM copy to put on my old XP machine which had been treated to a new Hard Drive. So I now have two Win 7 machines and they are great.
