Since for the vast majority of us this is a hobby we do for enjoyment, it really depends on what you like to do. For instance, I have no interest in trying to figure out a camera that has a phone book sized owner's mannual. I'm very comfortable with a camera that doesn't even have a compartment for batteries and have a lot of fun using it. Digi cameras hold no interest for me.
Negatives "have no value" one person says? I'll put my negative collection up against his digi files any day. Personally, I think there is value in both. I keep shooting black and white negatives and my collection slowly gains in value.
As for grain, yes there is a degree of subjectiveness as in any visual medium. For black and white, "texture" (grain) is an essential part of the art form. Also agree, black and white negatives are a real challenge to scan and post and still have the image look as good as a print coming out of the darkroom. That said, it's been 3-4 years since I actually printed. I now scan my negatives for mag articles and my own enjoyment. And agree, there are details I can pull from negatives with Photoshop that would be far more difficult to do in the wet darkroom.
To answer the original question, if you really aren't all that interested in shooting film, I think you will not be happy with the experience. If digi photography is what you are now uesed to, I think you would be wise to stick with it. For sure, if you do have a little fun with that old film camera, don't photograph anything that is important to you, and for sure shoot color, not black and white.
