I think I'm getting old :(
I was, well, not 'happy' but 'comfortable enough' and familiar with XP having used it for so many many years, hated Vista whenever I had to use it on other people's machines, I'm still getting to grips with all the nuances of 7, barely had the opportunity to use 8, and now 10 is on the horizon after they scrapped 9!
Where did all that time (and M$ R&D budget) go?
P.S. I remember when all this was just fields, now get off my lawn!
