I'm running build 7077 (which I understand is as close to RC 1 as anything) having progressively upgraded from 7000 via 7057. RC 1 installation is going to require the agony of a clean install and reinstallation of all the apps -including getting fresh downloads of the software where they were on line purchases, etc. Doubtless there is likely to be the need to do the same again when the retail version becomes available. Given the fact that my 7077 build is working very nicely thank you, I'm struggling to see why I should bother with RC 1 at all. Just wait for the final retail version, whenever that comes along. What does anyone else think?
