Yes, the Adam from Notion Ink http://www.notionink.in/index.php. It looks very impressive, but not released yet. Hope it's more than vapourware.

Aw. I though that obstreperous kind of fitted in context that you had used it. I think it's a bit of a shame that you didn't mean it!

As well as Android as someone else mentioned, there is also Maemo http://maemo.org/ which is being driven by Nokia. They are due to announce a new smartphone in the next couple of weeks which looks exciting.

Mer is a community led distribution of the Maemo code http://wiki.maemo.org/Mer

Mmmmmmm, carrots.

Ben Goldacre writes for the Guardian in the UK with his excellent Bad Science column. http://www.badscience.net/2009/02/bad-science-bingo/
He recently highlighted an ill informed rant by Jeni Barnett from LBC Radio on this issue of the MMR vaccine. They seem to be unaware of the Streisand effect in trying to shut him up and remove the clip from his website.
