but 10a already!? was 10 so bad they had to patch to 10a before release - or is this a marketing ploy to those of us who say we'll never buy till the second release?
They almost always have a quick release after the launch, this time they probably just had the deadline for getting product made, and they kept working, and were able to release a 10a by the time the product launch came about.
Instead of the link (above), I just clicked "My Account" --> "My Software" on this web site. If you have registered your software to your account here, then the available upgrades are all shown to you automatically just by going to your "My Software" page (along with upgrade pricing).
