I read it recently and liked it quite a bit. I think one of the things that stuck out for me is that he and Graham were taking this sort of 'quant' (using the term very loosely, as some people here do that, and I don't really know about it in detail) approach back in the 50ies - they absolutely poured over the stats in an era when that wasn't as easy as it is now. Now, Buffet is big enough to be able to do stuff ordinary investors can't, like buy entire companies.

In other words, perhaps part of his success belongs to a bygone era that won't come around again.
