If you had already shot film, you wouldnt have been the newbie anymore, and you would already known a bit about what you actually need, while people like me are completely clueless when we start.
For example, when I bought my first digital camera, a Panasonic compact (the merchant told me its the same as the Leica compact I actually had asked for), I believed stuff like:
1. Over time cameras get smaller, but will still yield the same results as old cameras, despite the smaller dimensions, thanks to the advances of technology
2. Everything about photography can be automated, you dont need to know about those details at all
3. Lenses are all zooms, having only one fixed focal length is just old tech and not actually done anymore at all
4. A good zoom has a lot of range
5. Leica makes better lenses than other companies
While today I would say:
1. Well, the quality of small cameras gets better too, over time. But creatively this isnt true - shallow depth of field is not possible with too small sensors, and the laws of physics (diffraction) limits maximum resolution on small sensors, and the lens designs with the least optical compromises dont offer much in respect to maximum aperture, which again points to a larger sensor for higher image quality. Thus there are very good reasons why one might want to have large sensors.
2. While some things can be automatted, you want to have at least partial control, since the camera ultimately cannot know what you want to do; also the more control the more creative possibilities, and full control isnt actually THAT hard either, you just need a lot of practice so you can do it in your sleep
3. Just like cameras, all lenses are compromises, making a lens a zoom comes at a hefty cost in other areas, especially size, weight and maximum possible aperture
4. This its only getting worse for zooms with large focal length ranges, which is why the best zooms have not much range
5. Actually the only thing Leica really is better at is making lenses really small through careful selection of glass. But other companies have their individual strengths, too, and can make just as good lenses if you are willing to pay the necessary price for high quality, and other companies have outperformed Leica, or done compareably good glas for a much smaller price.
