I use both (as do a lot of forum members) you might want to look at
Film Processing, Scanning, and Darkroom - PentaxForums.com
lots of good info to be found there. I prefer film for b/w. I still shoot c41 and e6 though as well. moreso with rangefinders and medium format, but i do use a couple of old pentax bodies as well. I grew up shooting film and still prefer it for some things, but i like the immediacy of digital sometimes as well.
the one thing i find film does is makes me slow down and think about every shot a little more as every shot costs me money (mind you I'd have to shoot an awful lot of film to justify replacing my medium format camera with a 645d)
I like the wait to see what i got as well. it's kind of like opening a present. I have a whack of backlog films to get to processing, I have an idea whats on them but i'm sure there will be lots of pleasant surprises (and probably some disappointments as well)
welcome back to the past. and those old lenses will serve you well when you buy a k7 or k5 or whichever body you choose. I shoot mostly with my old lenses now
