Well my feedback is I probably won't upgrade. As stated, the last thread on pricing led us to believe the upgrade price would be $15 instead of the $10 last week. I had been holding off upgrading as it still appeared buggy and I don't have time for buggy programs.
It is not that $26 is too much, but more the fact that I feel as if I have been mislead. "Prices subject to change" in my mind means 10 to 20% more, not 73% more.
Well maybe if I have a bunch of spare time, I'll install 11 and see if there are $26 worth of changes. But I doubt it.
