Well this is slick..
But I can't seem to decide if I it was worth upgrading or not. OS 6 used way more memory than 5 did. I went from 105 MB free to 58MB Free just by doing the upgrade. And Really the only thing I've noticed is that the home screen now acts like an iPhone and scrolls through different pages.

Also there appear to be no themes for OS 6. The default theme is lame and there is no way to configure it for "Today Plus"

So yes it's slick, but is it worth the nearly extra 50 Mb and losing almost half my free memory.... I don't know

Just my $0.02

Oh.. final note.. I do *love* the agenda view in the calendar. Never noticed that in OS 5 so I figured it's new to OS 6..
