Yeah, plus if you're on the Beta, the code-base is quite a bit different, so the patches aren't really an apples-apples comparison.
Some things may have already been fixed in the O drop that came out, it's pretty common for a bunch of latent fixes to get rolled out in builds like this, or at least it is in the Windows world, given that you expect the "Beta crowd" to be more accepting of larger payloads.
The update hosed my text and Outlook widgets, or at least made them "not so usable", somehow it's set all their fonts to much larger, and all bold. I also have a "notifier" widget, handy for seeing things like missed calls and texts, which now has a huge font, so clearly I need to go fiddle with these, and get things back to normal; hopefully they weren't using an undocumented interface that got changed or something...
It's stuff that would take me about 10 seconds on my Win Phones, but I'm clearly not a real Android convert yet, I have to go "muddle around" and figure this stuff out, again ;-]
