An old font that is legible at small sizes is New Century Schoolbook (not the Microsoft MT version). I am talking for print and/or high-dpi phone screens. It has an old feel to it, but it really is quite surprisingly legible. For lo-dpi screens, Verdana all day every day. I override all the web fonts to Verdana (and the size too) so I can actually read stuff. I just can't take anymore these days whatever weirdly-hinted tiny font the designer wanted to use.
