well, just put this into perspective, Berkshire Hathaway have lo

Please take a look at his latest annual shareholders letter, http://www.berkshirehathaway.com/letters/2011ltr.pdf

He admit that he was "dead wrong" about the timing of U.S. housing recovery in last year's letter.  And all the housing related business (under his management) didn't perform at all.  A similar example earlier last year, he was cheerleading the stock of Bank of America for his own sake. And you know what happened to BAC stock last year. Furthermore, he has been cheerleading American economy since early 2009 through CNBC/NY Times/Fortune Magzine. Well, the economy is still in the dump.    

I have been holding Berkshire Hathaway stock since 2000 and very grateful for his due diligence. I went to Omana(for the annual shareholder meeting in May) once to say thanks to him diectly.  By saying that, still want to remind everyone here, he is a smart business man and has the obligations from his shareholders to boost his stock price, or at least the book value against S&P 500 every year.      

BTW, he still lives in the same house he bought in 1958. It has 5 bedrooms, 2.5 bathrooms and 6234 square feet, the house was built in 1921. And I don't think he will upgrade his housing status, no matter how cheap those mansions will be, because he is very happy with his current home and won't spend any extra unnecessary money on it. And I respect that very much.
