Is there a LaTeX-like font for my other documents?

Have you considered LyX or some other word processor-like front end to LaTeX (Scientific Workplace, maybe).

I mean, not what you asked for, but you didn't say why you wanted this. Is it the interface? Or something else?

BTW-- That default TeX font is called Computer Modern, which might help you in your search. And in the wikipedia link I find

• Computer Modern typeface in TrueType format and OpenType.
• Computer Modern Unicode fonts X11 licensed

and others which are probably just what you need.

The Wikipedia article about the Computer Modern typeface has a bunch of links to Type 1 and OpenType formats.

You probably don't need to install all the variations. Just the 12-point size should work for most applications. The smaller sizes are hinted to make them more legible, but you probably won't need those.

Most of the links on the Wikipedia page point to the CTAN archives, so you may have to dig around through some directories to get to the TTF and OTF font files.

Edit: A friend of mine once pointed out that New Century Schoolbook set at about 110% of its normal width bears a resemblance to Computer Modern.
