This reminds me of that documentry Keanu Reeves just got done making, Side by Side. The trailer:

Now, I do not feel bad about film not being the popular format. I do think it is bad that it will be "Extinct". I do not hate digital filmmaking. Non-linear editing edivces like Pinnacle Studios are great and I love my little silver Sony Handycam. If anyone has watched HEARTS OF DARKNESS, and Coppola says that film will become a true art form when film is democratized and "a fat girl in Ohio" can make movies. But now, there is a certain look for actual film which is - as far as I know - not reproducable digitally. And Nolan is right in the trailer only in terms of Imax film stock. 35mm film stock can be reproduced digitaly as far as I am aware.
However now, unlike film, stuff mentioned above like the book vs. iPad thing is just ridiculous. The most obvious pro-book argument is that the iPad has a similar stigma to most screens - it is an electrical format. Sure, there is the fact that batteries could run out, but I am talk about another technicality: technically, monitors and screens are not on 100% of the time. They are actualy flickering on and off at a rate that the human eye cannot notice. Hence eye problems. No, give me my printed material. I want to feel ownership.
Oh, and skreeonk digital files vs. DVDs/Blu-Ray. Same thing: ownership. You cannot have things like a deluxe box set with special printed material in it and such with a printed file. You know, beautiful things like this:

Thankfully, people like Quentin Tarantino is still using 35mm.
Just a thought though, in regards to digital vs. film... in regards to the artistry. When you deal with digital, you can digitally alter the image any way you want to make it look like anything. With film, you have to spend a lot more time with lens filters and lighting and such. With digital, it is like you are shooting your canvas and then altering it with paints in the editing room. With film, you do not create the paintings as much as you have to go out, find them, and the shoot them (with the only thing connecting the shots being style and script). Of course, there are outliers to this philosophy, but you catch my drift.
