What resolution do you normally like to work at? My gf has a 12" PB and I have a 15". She absolutely loves her 12" and I like it a great deal, too. The reason I went with the 15 over the 12, was because 1024 x 768 wasn't a high enough resolution for me. I like to work at 1280 wide. But if you normally work at a resolution no higher than 1024x768, then I have a feeling you'd love the 12". Of course, you could also always hook up an external monitor if you needed a higher resolution.
