: I like to watch videos in at least 720p and in full screen.

You're not the entire human population, either, or the entire gaming population.

: Besides, you ever done any photography?

I've taken pictures of a few things I thought looked good... so, no.

: If you want a good looking image to put on your desktop as a wallpaper, you
: absolutely DO NOT shoot at 1080p - it'll look awful. You shoot at a much higher
: resolution and downsample it.

If you say so. I usually don't have a photograph as my wallpaper, and I don't see it much anyway.
Regardless of any of that, there are cheap ways to get video out, and there are solutions available for less than a hundred dollars that give pretty good quality, spending hundreds of dollars is not a prerequisite just to get any video out at all.
