Gizmodo is conducting a user poll: Do you prefer a single massive screen? Or a multiple monitor setup?
Once upon a time, I was partial to multiple screens. It's one of the things that got me into Macs: Back then, they were the only computers that could handle multiple screens as a single desktop, seamlessly. I would have Photoshop on full screen on the main one, use the right one for palettes, and the left one for other programs, like mail.
I’m partial to multi-monitor all the way. I’ve got a pair of 30″ Cinema Displays on my desk at work, and find it difficult to function with a single monitor anymore. I wonder what “Spaces” counts as (multiple desktops on a single display).
