I do digital photography for most normal stuff, and have a decent camera for that (not just my iPhone), but 35mm film is what I use when I'm actually trying to be creative. There's something oddly relaxing about shooting film that's not really there with digital. I think some of it is that, with $11 to develop a $5-10 roll of film with 24 or 36 shots, I'm forced to slow down, relax, think, and actually be creative. I can't check if I screwed up the shot, once I've pressed the shutter release it's done. And that makes it more enjoyable and relaxing. Even if I can get technically better photos with digital.
The other thing is, working as a programmer, I can only stand so much computer time, and it's all gone by the time I'm done with work. So sometimes the last thing I want to do is carry around a graphics-focused computer with a really good lens so I can capture digital sensor data to alter in Lightroom or Photoshop. It's the same reason I spend so little time playing video games these days, it has to be an unusually good video game to warrant my spare time sitting in front of a computer screen even longer.
