I've moved from 100% film in 2005 to probably 90% digital today. A couple of thoughts:
On shooting with film, I recommend it provided the cost isn't an issue. Anyone can afford to shoot film if it's budgeted properly. I'd say a person starting a film gear kit should go full manual as any camera offering automated features ends up moving a person away from the goal of shooting film in the first place. A fully automatic film camera might just as well have an electronic sensor in place of the frame of film. Also, I think there is a good risk the next ten years will see consumer grade still photography film for the average shooter disappear completely leaving only expensive full-core art products and unrecognizable pro-grade stuff. A film camera purchased today should be something a person would be happy to keep as a keepsake.
On digital malaise, it's not the digital part of photography we can grow tired of but the process in general. I guess a good question for any of us to ask ourselves is why not just set our digital camera(s) up like film cameras and shoot with them in that manner. Before leaving home, pick an ISO and WB, decide to shoot 36 shots, and then touch nothing but aperture and shutter speed while shooting. Digital shot like film, in other words. It's difficult to force oneself to do but turning off the image review on digital cameras is a major step back to film-like photography.
Finally, I think the issue isn't the type of gear being used but the occasional need to use different gear. A modern DSLR is a pretty sterile feeling device. I'm not sure I'd buy a K1000 because they're obviously expensive compared to other Pentax cameras such as the KM and KX. I think a small kit of Spotmatic gear would be an enjoyable change of pace. Regardless of the film camera used, I'm now thinking more than ever that I need to support Ilford.
