At a B&N with baaad WiFi.
Two hands-on items:
1) The hidden browser trick no longer works.
2) I haven’t seen this elsewhere: Tapping three times on Software Version will open up Developer Options! There’s a bloody ton of stuff in there.
Have also really peered at that screen. I’d love to have a tabletized one for Google Books PDFs.

Hey, I know this is rather old. But that hidden browser trick does work. It’s just slightly different now.
