I agree that top is way useful, but be aware there's been a security problem reported (granted, nearly a year ago) on "systems that have top installed with set user or group permissions".

I saw it here--unfortunately, there weren't many details or any further references in this report, which I guess is a compliment to the reader's presumed research skills.
