I'm familiar with his position on tech companies generally, as was kind of the premise of the comment (he doesn't "do" tech but does IBM and Apple and he's BFF's with Gates). What I didn't understand was there are several CEOs and executives of BRK portfolio companies on the BOD and why is there a not conflict there, but would be with MSFT...the reason, it seems to me is none of those portfolio company execs on the BOD report earnings separately from BRK.
