Warren Buffett just did a video interview with Reuters. 

Here's what he said about Microsoft (MSFT): 

Reuters: You’re always looking for value. What about Microsoft? I know you say you don’t do tech. But given that it has a forward P/E right now that’s below 10, it seems like a value play.

Buffett: Yeah. I agree with you. I regard myself as precluded from either personally or having Berkshire buy Microsoft because if something good happened the following week people would think Bill had told me. So I just see no way that we can ever buy Microsoft and be sure that we won’t look like we had some kind of inside information or something. So it’s off limits. It did look pretty cheap.
