What Mac setup should I recommend for my friend?

My friend has always used PCs, though is willing and eager to switch to Mac. Everyone he knows (including me) uses one, and he needs a new (virus free) computer desperately. He’s asked me to help him get set-up, and I can’t really decide between a Mac Mini with a Cinema display or an iMac (my favorite setup is a MacBook Pro with a Cinema display, but that might be too much for what he needs/wants).

He basically just wants to surf the web but added that his requirements are a nice (big) screen and a fast computer. Also, he doesn’t really take his computer out and about, so he probably doesn’t need a laptop. Suggested setups are most welcome.

Please don’t say, “Get a PC”. You’ll be wasting my time.
