Thanks! Glad to see it's seriously considered. I don't necessarily find the "blocky" fonts disadvantageous, but I wanted to try out the anti-aliased fonts as well. The more possibilities the better, and I'm going to be staring at Emacs a lot in the coming months.
You're right, the bold DEC Terminal isn't bad at all. I've left it commented out in my .Xresources file for future use, when my eyes get tired of the current font.
One possible drawback though is that Auctex would have to mark bold text with it using a different font (probably italics too), but that's a pretty minor drawback to having a nicely readable font, or even just a change of pace.
