Well then, here's hoping future updates will fix the issues. Not sure how stable the slow ring updates are, but could be something to check out if the issues are major, for you.
But seriously, with the issues VanMardigan has had (which apparently isn't that uncommon), with the issues I've had (minor and major ones, while on official releases, can't count fast ring as that's my own choosing, being a beta tester), I'm surprised Microsoft isn't bleeding more users than they are.
Also, I really don't get why they've branched 10586 and Redstone, I mean I get it, 2 different releases, but why spend dev-time on 10586, and not put all effort in the Redstone update to get it perfect, what's to gain from splitting your work force like this?
