I tried it for about a day and gave up. The letters were just slightly too small.
1440x900 sounded like a good compromise between the two for me, but I couldn't get it to work, at least without an app.
You couldn't get 1440x900 to work? That is supported in the display preference pane.
Exactly. Can you explain yourself there, Dayv? Did 1440x900 disappear for you somehow when you added 1680x1050? Because it shouldn't have.
