Someone recently asked me why I wrote so much about Apple, Facebook and Google. The reason is simple: These are the three most innovative companies (not necessarily in order of merit) in the tech landscape today.

There’s one other company that's very innovative although I don’t use it as frequently as the three mentioned, which is also why I don’t write about it as much - though I did write about it last week. I’m talking about Amazon.com that’s been really proactive lately.
