People hate flexible working spaces where you don't have your own desk, but they have at least this advantage: you can sit near the customer support people to hear some feedback when you can, and sit somewhere quiet when you need focus.
No giant monitors though? Typically I have the choice of "quiet side room" or "giant monitor at desk".
Well I'm only speaking out of personal experience, when I need focus I just need any old screen with fullscreen Emacs running on it, extra screen space just invites distractions. I'm probably a bit of an outlier there...
Depends how frequently you need documentation, and I do iOS so I'm typically running a large iPhone Simulator instance on screen as well.
I'll take quiet side room every time. I honestly question our need for giant monitors. The likes of Visual Studio is very wasteful of screen real estate.
Which was absolutely the case for us, at least for my first 5 years here before we opened up a new wing dedicated to people who are only sporadically on the phone (development staff in one form or another). I'm still distracted in this quieter but still open environment, but it's better than it used to be.
