Tired of Knuth's Computer Modern default LaTeX font

A few lines in your document preambule:

\usepackage[light]{iwona}

And you get a much more beautiful, compact and readable font for your entire LaTeX document. Give it a try.

Helvetica fanatics would also love:

\usepackage[T1]{fontenc}
\usepackage[scaled]{helvet}
\renewcommand*\familydefault{\sfdefault}

Ho and if you were not aware of this, there are plenty of other fonts available. [ http://www.tug.dk/FontCatalogue ]
