Well, after the first day, battery has stabilized and - indeed - seems to last longer than on 26.

I also found that, despite the removal of the refraction around the icon edges, and it's also dependent on background image color and brightness, there is a subtle but impressive glass reflection from inside the icon when you wiggle the phone about. It's growing on me. I still miss the icon shadow detail (e.g. the phone icon now all white instead of a gray/white gradient), but it's all growing on me.

I did see a bug, the eBay notification overlay is black text on black background and it's consistent, so I'll have to report that... still appears in the newly released Beta 4...

And another bug, when on lock screen and bringing up the PIN pad, the screen "flashes" instead of fades. It's random, and I need to articulate the description better before submitting. But with the latest beta now released, this one may have been fixed.
