For me, using O is a bit like driving a tank when all I wanted was a Smart car. I was very happy with OE, and as I still use XP, that would have been fine.
However, persuaded by the sage types on here, I moved to O and it has, so far, been trouble free.......(at which point I'm touching the wooden desk AND my head).
Eventually I will have to move from XP, and 7 doesn't like OE............
