May I ask why it's inconvenient? I find film much more convenient these days that film stores and processing is all available online, pay with PayPal not cheque, scans in Dropbox not a CD.
Taking into account inflation, I think it's probably no more expensive either.
It used to be that I could go into a shop near where I worked and drop the film (120 or 35mm) in the morning on the way to work and pick up the negatives at knock-off time or only a couple of hours later (I generally wanted to scan them myself). On holiday I could easily get 35mm developed and in many places I visited frequently I knew where to get 120 film developed as well, use lab scans and keep the negatives for scanning when I got home. Now all those places are closed (in Canberra, where my father lives, last time I looked there was nobody who processed 120 film at all at the retail level; same at the Gold Coast).
These days I can send film off and have it (a) delivered nicely folded, spindled and mutilated straight to my mailbox; or (b) have it sent as a package, which I can only collect at a post office which isn't open outside the hours I work. I tried a post office box but had difficulty actually getting things delivered to it and spent a lot of time tracking lost packages down. I can take film in to places in Sydney who will develop it and where I can pick it up. But "same day" isn't really possible without a lot of expense; and organising myself to go in and collect it is either transportationally difficult (train schedules at lunch hour being what they are, and parking in the city costing what it does) during the week; or it interferes with my other plans if I have to collect it on a weekend.
It used to be that I could shoot film for a week or three; pick a day of a convenient weekend to train it into the city, take some photos and drop that film plus the backlog at, say, Teds or three or four other stores. I could then wander to the pub, have a few beers (over maybe an hour), collect my negatives and be on my way. It doesn't really happen that way any more. Some of those stores are now shut and those (like Teds) that aren't are not processing things so quickly.
Black and white I can develop and scan myself. Digital or scanned, I can process and print myself on my own schedule.
It's not that the difficulties are insurmountable (far from it). Just inconvenient. I've just not been sufficiently motivated to be inconvenienced. Digital has been fine for colour (and my B&W conversions are, if not good, then at least better). Developing my own black and white has worked for me as well.
Colour film is no longer casual, it requires planning and an allocation of time. So I just haven't bothered so much.
