Getting myself set up with Scrivener 2.0 and just wanted to offer the font I’ve found most comfortable for long writing sessions:
You can download Meslo for free.
I also set up my full screen editor to have a black background and totally hide all other windows. I’m currently using an orange font color in full screen.

I’m an ardent fan of Latin Modern Roman 10, at 16 point (only with the doc zoom at 100 per cent). Clean, classy and free.

Latin Modern Roman, a very good one. Thanks!

Scrivener’s manual uses LM Roman Dunhill variant for the chapter titles.

I like sans fonts for screen, serif for paper. I tend to switch between Verdana, Tahoma, and (whisper it) Calibri for the screen. I did have a long period of using the Bitstream Vera Sans Mono sort of fonts, but I’ve gone off them now.
For serif… someone on here I think mentioned Calisto MT, which is very nice. Constantia and Minion are very readable too.
I like Caslon for almost everything, probably because it was the primary face in a magazine I worked on back in the days of hot lead and make-up forms and pulled press sheets.

After a lot of experimenting I settled on Verdana – not very original, but I find it the easiest on the eyes for long writing sessions. – Jane
There are lots of varieties of Caslon – not so disparate as the thousands of dissimilar Garamonds – but the best for digital use seems to be the recent “Williams Caslon”:
Thanks for the note. I’ve seen Williams’; it looks very good, but I’ve not come across an available copy. For now, I’m using the Adobe version.
ps
Thanks, Ioa. You’re a champ.
The Williams version seems a little more solid than Carol Twombly’s Adobe Caslon, which extra touch of darkness is always good for digital, since digital lacks the ink squash that makes letterpress so lovely. Cf. Poliphilus from Monotype; they kept the squash. (Though it is a very strange font!)
I wish Ms Twombly hadn’t disappeared into the Sierra Nevadas in 1999 like Jimmy Cagney in “White Heat”… she could have designed some great fonts!

At $210 USD, it is definitely an investment, but I agree it’s a lovely rendition of Caslon. I once tried to play a bit with Apple’s font tools to create an impression of letterpress, or at the very least, typewriter strikes, on a digital screen. It’s a difficult combination of manipulating the shadow tool to create a bit of a squash effect. You can do a much better job of it with Photoshop, which allows you to apply grain and strike profiles to the halo, not to mention variation with a an overlay fill filter, but of course that only works for static text.
