Front and center on my desk is my 21" 2011 iMac with a 20" Cinema Display hooked into it on the left. Under the cinema display is my little server, an original Apple TV hacked to run OS X. Underneath the iMac is my AirPort Express, and to the right is my 20" iMac G5. My 2012 MacBook Air is often found on my desk, and my 2006 MacBook Core Duo sometimes makes an appearance.
As for iDevices, I have my 32GB iPhone 5, 32GB iPad mini, third-generation Apple TV, and 10GB third-generation iPod.
For vintage things in the collection, I have my original 4GB iPhone, iMac G4, Macintosh SE, and Apple IIc+.
