Due to unpopular demand, I might have to rethink my tongue... To be fair, I was never fully set on the idea specifically because it gave an unnecessary hard time dealing with its layout relative to the controls. I may just put a standard pacman play field background type-of-thing.

Yes, I'm strongly leaning towards a vertical 4:3, as mentioned above. Just because most games I intend to play on it will be the old, vertical ones. So I'm getting a taller 20" 4:3 than I'd be getting with a 28" horizontal 16:9.
As for the keyboard... Well, as far as I know, most vertical cabs have some sort of keyboard... usually hidden under the CP. What I don't know is how often it's actually being used. However, the keyboard I've pointed to is actually pretty slick looking. When turned off, it's just a glass looking surface... similar to what a Plexiglas covered CP would look like. Turn it on and the digital keys light up. So I'd add a small USB power switch right next to it (or hidden somewhere) to quickly access it; but most of the time, it would be turned off. I know it's unconventional but I'm at piece with myself on this one...

I'm willing to live with the consequences... unless somebody brings up a functional challenge.
Finally... I don't want to sound like I'm ignoring your inputs, as I truly appreciate the time you guys take... but I want to stick with 2 joysticks. Definitely flexible on the layout and the number of buttons though...
