I think this LF x 35mm thing is a matter of priorities.
If the best print quality possible is top priority, then LF, ZS, Azo, PMK makes a lot of sense.
If you priority is easy of use, to be able to shoot quickly, then 35mm, compensating development are the way to go (besides it's easy on the backbone...).
And if seeing results at once is the priority, then nothing compares to digital.
Just a note: beside the Pentaxes I use a Coolpix 2000 (birthday parties and the like) and have not used lately an Olympos Superzoom 330 - very good for vacation photos.
