Please help settle an argument: my son 'just' heard about the Raspberry Pi and was telling me about it. I was really surprised he hadn't heard of it, given his interests and background and I said, that it had been around for a very long time.
He searched and the blog gives an initial release date of February, 2012.
I thought I remembered hearing discussion much earlier than that on the Ars Forums and searching for "Raspberry Pi", I found a post on May 9, 2011 mentioning it as a possible solution to something, but with no detail.
I seem to remember discussion even as early as 2010.
Were there pre-release versions widely available?
