There will be certain points of time when everything collides together and reaches critical mass around a new concept or a new thing that ends up being hugely relevant to a high percentage of people or businesses. But it's really really hard to predict those. I don't believe anyone can.

Smart tech investor thinks about: a) future product roadmap, b) bottoms-up market size & growth, c) talent and skill of team. Essentially you are valuing things that have not yet happened, and the likelihood of the CEO and team being able to make them happen. Finance people find this appalling, but investors who do this well can make a lot of money.

Practically everyone is going to have a general purpose computer in their pocket, it's so easy to underestimate that, that has got to be the really, really big one.

These days, you have the option of staying home, blogging in your underwear, and not having your words mangled. I think I like the direction things are headed.

I enjoy not being a public company.

At Microsoft, they all rock back and forth like Gates, they wear the same glasses, they have the same hair style. Maybe they grow them in tanks.

Great CEOs are not just born with shiny hair and a tie.
