Completely agreed, things were so much better when Macromedia owned Flash and the support was great on the Macintosh.
I have to disagree, I've been a Flash developer for a handful of years and I must say that since the days of Future Splash, the introduction of Actionscript 3.0 in Flash CS3 was the biggest leap that the Flash platform ever had! Actionscript 1 and 2 made no sense at all (imo), it was completely incoherent as a language and just horrible at doing basic stuff like loading and managing XML data.
The thing that still bothers me is that the performance of Flash Player 9 on Mac OS X seems slower (slower, not slow) than on the Windows side. I think that must be Adobe's fault and I've read that the next Flash Player 10 will have a big performance leap on the Mac side, I seriously hope that's true.
As for people saying that CS3 had no high value features I must say that, as far as I'm concerned, there was one main feature that justified the upgrade: Native support on Intel Macs! I had a horrible experience trying to run CS2 apps through Rosetta on an Intel Mac so the performance increase for me was more than enough, coupled with the better integration of Illustrator/Photoshop with Flash, win/win
I just hope that people Adobe can get Flash where it's supposed to be. Flash nowadays is just seen as an annoyance and a way to make animated/obtrusive ads that pop-out from everywhere. That is not what it's supposed to be!
Flash can be a very significant part of the internet if done right!
The problem is that the world is filled with "2 weeks watching tutorials" Flash "developers" that don't really know anything about Deep Linking, SEO, having a liquid layout, XML driven website structures and all the good basics that conscious Flash developers worry about.
Apple and Adobe have to solve their issues with one another.
What the hell am I going to do if Flash CS6 goes Windows only? Use Windows as my work OS?
Please....... nooooooooo
BTW, sorry for the long post, I had to vent...
Exactly why I'm happy that my browser has a built-in "disable Flash" button that's almost always on.
Search for "flash blocker" to get rid of annoying flash ads.
I understand your pain... I am a Flash developer and even I have FlashBlock installed on Firefox because of the abuse that people use Flash for. But that's the same problem with a whole bunch of different technologies, I guess dumb people and bad professionals are everywhere right?

I'm just saying that it can be done right, if it's the right team building the UI and programming the website/application.
