Mini survey: I have six

Yesterday a friend of mine pointed out that I have six computers which I all use regularly: a laptop for work, a laptop at home (for photography and hacking), a netbook, a backup/file server at home, a webserver and a smartphone.

Is this too much, do I need to go into rehab? Or is the average much higher? How much computers does the average IT-er have (and why do you have them)?
