Obviously things like the view out the window and the amenities in the neighborhood are not always the easiest to control, and have huge impact on the price and availability of an office. So I'll focus on the little things that make a huge difference for me at work.

- Coffee, tea, and good water available. I do like taking breaks at times to run out to the coffee shop, but sometimes I just don't have time or energy or money, and being able to step into the kitchen and get what I need is great.

- Full spectrum "natural" lighting. I'm lucky that my office has tons of windows and a view, but when it gets dark or when I'm working on something detailed at my desk, a good full spectrum light is really important both for accurate color and just to be nice to my eyes.

- Dual computer monitors. I suppose this is a bit subjective but I go insane if I don't have a second monitor (doesn't have to be anything special, mine's just a small square) to put things like email and music and reference documents on while I work.

- Refrigerator space. I try to bring lunch most of the week instead of eating out, and more often than not it's leftovers from dinner with other random things thrown in... being able to just toss it in the fridge in the morning is great.

- A comfortable desk chair. I don't know about the $1200 chair (I certainly couldn't afford one at this point) but make sure it won't hurt your back after sitting for a long time.
