Okay, gonna see if I can do this with my "PDQ" PowerBook G3, running Mac OS 9 with Classilla and Mac OS X 10.2 with Camino. Already imported my latest digital camera pics to iPhoto 1.1.1.
I'll use my iPhone solely for phone calls, text messaging, and photo/video. (I mean, I *COULD* carry around my ancient point-and-shoot, pocketable camera, and I *COULD* use an ancient flip phone; but why not use one device that fits easily in my pocket? And a majority of my contacts also use modern iPhones, so iMessage-over-data instead of old-fashioned text messages and FaceTime Audio instead of actual cell phone calls are the norm. It would confuse my family if they couldn't reach me via those.)
Verified that I can log in to my email from Camino, that's the only "really important" thing. Worst case, I can live without anything else. But, while MacRumors forums are painfully slow, they do run on Camino. (I can read, but not log in, on Classilla.)
