So, the upgrade story goes: DOS, Windows 3.1, Windows 95, Windows 98, Windows ME (I think), Windows XP, Vista (I think) and now finally Windows 7.
After trashing two laptops and some cursing because over 70% of the applications I used did not work on Vista I gave up a month into my testing. So, I turned the other chick and made sure I downgraded all my system to use XP SP3 a more stable and proven system. A few months ago I decided to give Windows 7 a try and what a pleaseant surprise it was.
The short version, it fixes a whole lot of problems ...
