Has anyone ever seen antialiased font with emacs?

Me. Many times.

First I use TrueType fonts. They get rendered and anti-aliased by the X server.

Second Carbon Emacs for Mac OS X uses a Quickdraw based anti-aliasing for scalable fonts too.

To see the difference either use in one frame a vector based font or fontset (TrueType or PostScript, or OpenType if your X server supports this) and use in another frame for example bitmapped fonts that GNU supplies since ages (-etl-fixed-*, too -schumacher-clean-*, -mutt-clearlyu-*). Or invoke C-h H and then check with C-u C-x = the glyphs.

There is another approach too possible: first invoke xlsfonts and list all monospaced fonts with iso10646-1 encoding, as an example, size: 12pt or 14pt or 17pt. Among them you'll probably see patterns like this one: -0-0-. This pattern tells you that this font is built from a scalable (vector based) font, i.e. TrueType, PostScript, OpenType. The other fonts are bitmap based, come from bdf or pcf files. You can have Courier or Lucida Sans Typewriter in both formats -- and find whether you have anti-aliasing on your platform.

I have with my X server (XFree86 version: 4.3.0). And I do prefer the bitmapped fonts! They look sharp and crisp, the glyphs are perfectly exact positioned.
