I was wondering about Paul's comment on using Arno Pro, given that it is supposed to be a brand new typeface.  It turns out it is bundled with a number of new Adobe products.  Futhermore, a pre-release of the typeface version was included with the Photoshop CS3 beta.  So I opened up Fontbook on my iMac, and indeed, I have a version of Arno Pro to play with.  I'll have to prepare some comparisons in the near future.
