Don't forget the mobile phone which most people always carry with them when away from home.
In the film era I had an Pentax camera (MX?) with a range of lenses and processed B/W film myself. Over time I found it became more of a burden to lug around so much gear especially when on holiday or going to "special" events and it became used less.
Along came digital and with smaller cameras with auto everything, plus manual control if required. I bought a fairly expensive compact digital camera with additional lenses but after some initial enthusiasm using it I found that it still became a chore carrying it around in its protective case. My enthusiasm for taking photos with a dedicated camera somewhat waned preferring to enjoy the actual moment rather than taking a record of the event/place.
I no longer take as many photos as before but I do have a camera on my phone and that fits in my trouser pocket. The camera on my phone takes more than acceptable photos the majority of the time. It hasn't got the performance, say, under low light nor does it have a long telephoto lens capability BUT it's not a hassle to carry around.
