I shot slides for about 30 years, first Kodachrome then, after some experimentation, Fuji Provia starting in the late 90s. I don't think I've shot more than 2-3 rolls of color prints in my lifetime, and haven't touched B&W since high school photo class.
What drove me to digital was the increasingly slow and careless processing options and closing of local labs. I used to be able to drop off my film in the morning and pick it up after work (heck, until 1982 or so we could get Kodachrome processed here in Chicago, at a Kodak lab, overnight!). By 2008, I was looking at 2+ weeks turnaround time, no matter where I took it - camera store, big box retailer, Target, etc.
Haven't touched slides since.
I did however buy some Tri-X for my Nikon Rangefinder. 😉 I really need to shoot it and send it in...
