I think this is a case where some people will like it, and others won't.
Personally, I don't use the bilinear filtering option either. I just
added it since it only took a few lines of code.
My real reason for using OpenGL was the alpha-blending, and more
importantly, the aspect ratio. I think everyone can agree that picture
1 looks a lot more authentic than picture 3 (which is way too wide).

I tend to agree, since I like the authentic look over everything else.
Besides, most people remember their Atari experience differently.
Whether they were using crappy machines (with bad power supplies) or
crappy TV's, it's next to impossible to re-create it :)

Me either. But it can be (de)activated while the emulation is running,
and it was so cheap to add, so maybe some people will like it.
PS: If I could get the &*&$# sound problems fixed in Stella, this is the
type of stuff I really want to work on; filtering modes and in-game
GUI's. But the default, no-frills, pixel-perfect mode will always be
available.
