Camera for journaling?

Hi, I was just wondering if anyone has any suggestions of a camera I could use for journaling? I already have a film camera which I use for learning technique but my main cause for getting into this hobby is for a preservation of memory. I journal a lot but I wanted to put some photographs throughout the text, because as a small child I thoroughly enjoyed flicking through my parent's photo albums. The camera's I am considering include:

- Instax Mini 8 ~ cute camera, takes instant photos (I love having the physical thing in my hand) but the film is expensive…
- Polaroid z2300 ~ digital camera with ability to take instant, film is less expensive than Instax
- Nikon Coolpix So1 ~ super tiny camera (that I can take anywhere), going for supersupersuper cheap at a store near me… Stock will probably run out soon though, no instant but could get them printed

Any advice for which one I should go for? My main purpose is to include tangible photographs throughout my writing, something I can look back upon in the years to come:) Thanks xx
