One of Silicon Valley's last true characters has signed off - Sun founder Scott McNealy has sent a final goodbye memo to his staff. In his own words McNealy is "a big mouth who is always ready with a clever quip" and his swansong email does not disappoint. He said the last four years (since he left the company) had "not been without serious withdrawal". He said: "So, to be honest, this is not a note this founder wants to write. Sun, in my mind, should have been the great and surviving consolidator. But I love the market economy and capitalism more than I love my company." He said he hoped the rest of the US economy would fall in love with capitalism again soon.
