For me, JPEG in, JPEG out - it's all I get, after all.

Storage is cheap, keeping RAWs isn't an issue, I shoot RAW plus JPG, most of the time for events JPG are widely enough. and I often delete RAW files afterwards.
For important events and when you need to edit the photos RAW is essential, so I always keep the RAW files (only for the keepers though)
with storage prices low, storage space is not an issue

For me it's nothing to do with storage. At this point I wonder if I'll ever go back and look through the images I took 20ish years ago. Beyond that, I can't remember the last time I pulled out the slide projector!
