Can it be human?
Absolutely - humans can use any user-agent they want.
It could be someone using Safari on OSX, for example.
I'd guess it was probably a bot and might look for other signals.
Alternatively, I might restrict it to an "obsolete browser not supported" page.
What's wrong with old software?
Some of it is a security risk, some of it is so outdated that it is effectively useless.
But if you said "some old software is still useful, risk-free, fast and efficient" I would agree.
Unless you were talking about IE6, of course.
