For me, the reason is different. I don't mind people walking or even talking nearby, but I really hate the process of pack/unpack. Before work, I need to setup the laptop, the cables, the IP to access my local server from Android, get notebooks, pens, ohh my earphones, and a lot more, only then I can jump to work for maybe 2-3 hours (I feel a little uneasy to stay longer in the cafe). If you are working alone, the bathroom is more complicated. Oh and the outlet. And internet... It doesn't work for me. Office is my only option, because I want everything ready to start immediately.

Me too. I tried the library but it took too much effort to setup and tear down every time I needed to move (such as restroom break, lunch, quick break). Also, it would be impossible to have access to a nice large monitor.
