I've just read an entire thread in your blog, discussing (among other things) OWA support for Firefox.
All I saw were excuses. Excuses about priorities/time management/ROI etc. When will you guys get it? We don't want excuses, we want action!
And I DON'T want to use OWA light. Why should I use the second best?
Anyway, I can't use IE, even if I wanted to, as I'm working on a Linux workstation.
Come on, you're the PM, aren't you?!
Damn it, make a decision and allocated the people to support Firefox in the premium version!
For us, Firefox/Opera/Whatever user it's far more important than most of the other features (which we won't be able to use anyway..)
Not to mention that combining the two projects (Light+Premium) can give you the personnel needed for the additional development/support.

I'm a different Eric. Same basic problem. I have a mac, a handful of PC's and a linux box. It's a pathetic shame the the people at microsoft don't get fact that the world doesn't all work on PC's. MS needs to address this. Google and others are catching up fast...
