I updated OTA here in Penang about 24 hours ago.

Got the usual 'Use a PC' message.
I used apt-get upgrade to figure out what's the problem. It was a couple of packages. gstreamer-plugins-extras-bad, fmtx-enabler & libgles1. I had to remove Extra Codec Support, FM Radio, Tuxrace, gltron & Brainparty to make it work.

Had 60MB free on root & the update took almost 20 minutes. But I was relieved when it completed without incident. Didn't loose any data, just some settings reset. I was surprised that even my custom boot video was still there.

I didn't notice any different is performance or stability, but love the new features.
