Enough lurking in this thread for me! Time to post my setup! Apologies for the bad quality photos, I used my camcorder to get the pictures as I don't have a normal photo camera.
I use my iMac as my main computer and my PowerBook G4 as my secondary for when watching movies on the iMac or vice versa. Yes I do use an exercise ball as my chair, I have to get a real chair though, this thing really hurts my back.
I use my iMac G3 as my bedside computer, it's nice for when I wake up so that I can quickly check my emails and whatnot without having to get up and turn my computer on
The iMac is held up on 2 PowerMacs, one is a B&W G3 and the other is a G4, the other G4 you see in the pic (the one against the wall) runs my Home entertainment setup and has all my movies on it, you can see it running on my 37" T.V in the first picture.
And last but not least, my Apple Studio Display with my WIP Halo 3 ODST Rookie Helmet ontop of it., It's either 15" or 17" but I'm not sure, can someone correct me on that?
