A few years time? Not likely, although we'll likely see less "1-hr photo" type setups in "normal" stores (drug stores for instance). But past that digital is not where it needs to be for film replacement, we're only now getting to the point where digital is a reasonable replacement for 35mm, but there is no digital answer to medium and large formats.
Normally I'd recommend digital for newbies, the cost to start is high, but easily made up, plus it helps you to become a better photographer as you won't be worried about taking risky shots, for instance I have no problem going outside and taking 200 pictures of the moon, it doesn't really cost me anything to do it. On film that would have cost me around $60-70 to do.
However, if you want to do star trails and that type of photography (ultra long exposure times) I'd say get a film camera. Digital sensor noise (ISO noise) is a function of many things, one of them is exposure time. The other issue is battery life, it's one thing to get 700 shots out of a digital battery charge, but will it hold the shutter and power the camera while recording the image for 6hrs while getting a star trail? For that you're best off with a really old film camera.

| This trick should be a good workaround for long exposures w/ SLR cameras that lack mirror lockup to avoid the camera shake/vibration caused by mirror slap -- in-camera mirror lockup/pre-fire does a similar thing, except the actual shutter open is delayed by a couple secs after the mirror is lifted. However, it doesn't replace mirror lockup for cases where your exposure times are short or relatively normal (but not nearly short/fast enough to avoid the impact of mirror slap), especially when using a big, long lens. |
Mirror lock up isn't going to be needed on a long exposure (say over a minute), the milliseconds that the camera is shaking from the mirror slap isn't going to expose anything if it takes minutes/hours to properly expose the rest of the picture.
The hat trick is good, and no need to worry about camera shake once you have the lens covered.
