Oh wow, I was thinking about making a thread about fonts a few days ago.
I actually like Times; I suppose I'm a bit of a traditionalist when it comes to fonts.
I've recently started to use Helvetica Neue for all text documents that I read on my PC. It looks much better on screen than old-fashioned Helvetica, which is definitely a print font (to an extent, Times is more of a print font than a screen one as well). However, it looks bad when the font size is small, so for browsing I use Arial Unicode MS for sans serif, Gerogia for serif and Courier New for monospace with a minumum font size of 16. Despite the bad press it gets, Arial (and to a greater extent, Arial Unicode) is a perfectly fine font for reading on screen.
As for serif vs sans serif, I've heard that serif is better for printed text and sans serif is better for reading on a screen. Personally I think that sans serif is better for reading on screen and for short pieces of printed text (such as billboards and such; Helvetica is brilliant for these purposes) whereas serif is better for walls of printed text such as books and newspapers because the serifs make the lines seem more "defined" and easy to follow. I suppose this is why one hardly ever sees novels printed with sans serif typefaces.
Also, I don't hate Papyrus.
