Do developers really need a second monitor?

Annoying, the author doesn't seem to answer his own (@#*&$ question with anything substantial. I'm hoping by posting here that something other than the Atwood Developer BoR can be cited as something valuable...one study is hardly enough to convince most managers. :(

Fun to read and interesting, I don't read this as an article, It appears more to me a nice story telling than an useful advice.

Personally I can't feel really productive using multiple monitors, I always forget one of them and focus on just one.

This maybe related about your work, if you are multitasking you may find it useful, however I don't naturally program that way I force myself to focus and this is very difficult with two monitors.

Actually, having switched to a 27 inch imac (2560x1440), I find that one monitor is actually better than two smaller monitors. I was hoping the article would come to that type of conclusion. Alas ...

Some developers prefer one monitor, some prefer more than one. Some managers understand the needs of the people they manage, then again, some don't.
