Jad, you are right, and had you purchased the shares in 1998, you'd barely be ahead after 14 years! That said, had you waited another year or two to buy after 2007, you'd have done quite well.
Moral of the story: Timing is everything when it comes to your buy price. Don't overpay for even the best of companies. You weren't the only one arguing against BRK's supposed "value" in 2007. There were a few of us who agreed with you, most notably HC. That doesn't make BRK a bad hold, particularly if you owned it at much lower prices, and/or used options at opportune times to generate a return on your holdings.
