2-3 at most. #6 and talking mostly of cameras but only with friends who have the same hobby as mine. For part-time photography work, gear talk is minimal. It's mostly on how to engage the client, techniques and poses. It's more of a creative conversation than technical. Most of the time (when not working), I just bring my G11 so as to minimize the contents of my backpack except when our family goes to a place that's very interesting. For everyday photography, I find my G11 sufficient. If any smartphone will have manual controls + comparable IQ, I'll immediately switch my G11 for it.
