I guess my situation is more of a home based media business than a home environment, but I have 4 CPU's switched with cpu switch to a single 24" monitor 1920x1200 In addition I have an IKAM 3 x 16x9 video monitor rack, a DVCAM and betacam SP deck. Dual Blu Ray drives, a MFC 11x17 printer and two Microboards DVD printers/ burners. On my desk, I have a Dell M1210 laptop. ipad charging Dock and a cellphone charging dock. The CPU's are: a business software/ web surfing CPU, an HDTV video editing and Blu Ray burner, An SD video editing CPU and a secondary SC video and audio composing CPU. Audio monitoring is a stereo mixer to a 2.1 speaker system and a dedicated 5.1 speaker system off the HDTV editing CPU.
If I didn't do Video production and post work often 2 projects ongoing at the same time, I would just have a laptop with a DVD / Blu Ray burner and my ipad.
