I've been using 3.5 for a few weeks. I like it, haven't noticed much difference between beta and final.

Flash is whored far too much, I agree with you on that. It makes it so pages cannot be indexed, no copy paste, no anything. For some things, this could be okay, but for entire websites, it's stupid. Perhaps HTML5 media support can replace this. I have no idea though, I haven't read much on it yet.
