Its an awesome update. Totally worth the pre-order price, or the discounted price if you are a previous owner.
To those of you complaining about purchasing it again, think of windblows.
You just buy Vista today, Windows 7 comes out next month. What's the upgrade fee? It's very rarely free...
If you can't justify the $$$, Beersmith 1.4 is still a fantastic program.
I'm a beta tester, one of maannnny. If you have specific questions I can try and answer them.
