The Raspberry Pi's are now shipping in volume and are gradually spreading. The site at raspberrypi.org has links to a map showing the spread worldwide. This post is being edited from a Pi on my desk and using Midori as a lightweight browser.
After all the hype: it works, it runs Debian Squeeze well and can update from Debian apt repositories. Graphics drivers are non-free but I'd hope there would be a way to work together with the development team to get them put into the non-free repositories.
Blogger doesn't like the browser and suggests an update to Google Chrome but that's life, I suppose :(
