Installed 7100 64b and it works fine. Not ground shaking from 7057 (actually), and simply better than the MS free original public rc in that they added the gadgets, wallpapers, themes, ability to manual add search providers, and a longer expire date 3/2010.
Other than that, I see nothing extra that would shake most worlds.
Oh, the same keys DO WORK with 7100 as well as all the previous releases.
I think MS gave away the original release and leaked the updates simply to avoid the mess with the vista final release.
Few programs and hardware worked after vista was released for sale.
It took vendors such a long time to play catch up.
By releasing Win7, vendors could prepare, and end users could begin the rant to vendors for updated software and drivers. Hopefully by the official Win7 release, most compatibility issues will have been resolved. Hearing red eyed rants from end users might just be the thing to kick vendors into gear with driver and software updates before the price tag is added to Win7.
If vendors snooze, they lose. People will simply jump to software Win7 ready to go.
I think MS knows exactly what they are doing... We end users will be the ones to benefit.
