Not sure if this is a wrist-slappable comment, but there is this wonderful thing called virtualbox, You set up your environment install your beta and away you go another 60 days of play.
I am sure Adobe's plans to release FB4 are now in high gear, fortunately they don't do the M$ trick of announcing a release date then delivering 18 months later, I would not be surprised if a release date was given soon hopefully with a release date for this quarter.
DCD is a new thing and will evolve, its up to the community to push for the enhancements they want added to the FB environment.
The market place is big enough for both flex and silverlight, I just hope that both products maintain their own identities, as a developer its nice to have choices, i'm not interested in product wars i just want products that encourage me to be a better developer.
The name change, honestly I wasn't happy with it but then I wasn't happy when my girlfriend changed her hair color, funny thing is blonde or brunette made no difference to her saying not tonight, and when I open flashbuilder i'm still a flex developer so nothing for me has really changed at all.
Anyway don't give up on flashbuilder, I think it's worth the wait.
Thanks for the input. I considered vbox but wasn't sure that flash builder 4 would run fast enough in that context. I'm building a new dev workstation box today and that might help; in any case it'll be able to host a new trial.
But anyways, I still think it'd be smarter if Adobe made access the betas simpler. I am sure they have reasons for the choices they've made; this is input for them to consider.
I like what you wrote about the name change <g>.
