I'm glad to see the positive reactions.
Just to clarify/answer a few things:
1) BC3 is not available for the Mac; just Windows and Linux right now.
2) If you purchased using DonationCoder's discount our records should show it. Our free upgrade window has always been 12-18 months, and when Mouser wrote his review we expected to hit that window. We decided to take more time to polish it and add extra features instead. If you think you deserve a free upgrade anyway, just email sales and I'm sure they can help you out.
3) We haven't made a big mailing about the official release yet because we already have plenty of support, sales, and upgrade requests to keep us busy. I think the plan is to email the full list in a couple of weeks once the initial rush dies down a bit. We did mention v3 the 2.5.3 announcement email, and emailed the beta list a few months ago.
4) BC2 sessions and most settings can be imported into BC3. The only thing that can't be converted automatically is custom comparison rules (unimportant text, etc), due to changes in the way those are handled.
