Georgia is a modern serif font that was designed specifically for onscreen legibility, as was Verdana (often misread as Veranda). While Verdana has become a staple Internet font, Georgia has not (as of yet). I believe the best way to use Georgia is as a substitution to Times New Roman in your web browser. It is a larger typeface relative to Times, but it is much more elegant. Here's the official bio on Georgia by Microsoft:
Designed in 1996 by Matthew Carter, Georgia is the serif companion to the first Microsoft sans serif screen font, Verdana. It was designed specifically to address the challenges of on-screen display and hand-instructed by leading hinting expert, Monotype's Tom Rickner. Georgia was jokingly named after a tabloid headline "Alien heads found in Georgia." If you must have one serif face for reading on a computer, then you've found the best one right here.
It also helps if you customize your toolbar and add the text size up/down icon, as seen here for Internet Explorer. Here's the bio on Verdana by Microsoft:
The Verdana typeface family was designed specifically to address the challenges of on-screen display. Designed by world renowned type designer Matthew Carter, and hand-instructed by leading hinting expert, Monotype's Tom Rickner, these sans serif fonts are unique examples of type design for the computer screen.

In its proportions and stroke weight, the Verdana family resembles sans serifs such as Frutiger, and Johnston's typeface for the London Underground.

The Verdana fonts are stripped of features which are redundant when applied to the screen. They exhibit new characteristics, derived from the pixel rather than the pen, the brush or the chisel. The balance between straight, curve and diagonal has been meticulously tuned to ensure that the pixel patterns at small sizes are pleasing, clear and legible. Commonly confused characters, such as the lowercase i j l, the uppercase I J L and the number 1, have been carefully drawn for maximum individuality – an important characteristic of fonts designed for on-screen use. And the various weights have been designed to create sufficient contrast from one another ensuring, for example, that the bold font is heavy enough even at sizes as small as 9 ppem, or 7pt on the screen.

Another reason for the legibility of these fonts on the screen is their generous width and spacing.

At low resolutions, because of the limited number of pixels, letters cannot differ very much. But often the smallest differences can change the whole look of a page, or a screen full of type.
Andale Mono also works well as a monospaced or fixed font. Designed by Steven R. Matteson for Monotype and formerly called Monotype.com, it is now called Andale Mono.

Andale Mono, Georgia, and Verdana are no longer available for
free as of August 12, 2002. Still, you can probably find these fonts elsewhere, like in a web browser, Microsoft Reader, etc...
