When I first became interested in type, monitors typically had a resolution in the neighborhood of 72–96ppi. My MBP, according to Apple's support site, has a resolution of 226ppi. Back in the 80s I had speculated that 300ppi was a minimum for good typography, but maybe it's my aging eyesight, but I find that what I've got on my laptop is more than sufficient to use most typefaces (and the fact that there's no pixel spread likely helps with the slight lack of resolution), although more subtle designs, like Optima really want a resolution of at least 1200ppi.
