I have a brand new iMac (top of the line, cost $4,000). Around it I have two 24-inch Thunderbolt monitors. Cost about $1,000 each. Over it I have a 65-inch Vizio TV (they loaned that to me for my studio as a promotional thing). On my desk is a Toshiba Android-based Tablet (at the moment, my Samsung died and I need to send it in and get it fixed) and an iPad. Over to my left is a MacBook Air and a Google Chromebook. On my screens I keep Twitter, Salesforce Chatter, Google , Facebook, Quora, and Gmail up all the time. Most of the time Spotify and Skype are running in background.
