There is dstat missing from the list. It's a tool that shows the information of vmstat, iostat, netstat and ifstat in a clearer and with colors ;)

I use it primarly to see the used bandwidth in real-time. It's better than ifstat for that job.

The man page "See Also" section for dstat is practically a blog post in system monitoring itself.
