MBP13 for everything...
Due to traveling, I got a 2010 MacBookPro 13", 8GB RAM to replace my trusty 2008 iMac 20". Apps: I live in Photoshop & Dreamweaver...those two pay the bills. Of the six Macs I've owned since '99, the MBP13 is my absolute favorite. As for what I'll get when it's time to upgrade: the MBP13 is still closest to exactly what I need out of the whole Mac lineup, with the MacBookAir 13" a very close 2nd...two thumbs up for 1440x900, weight and curved edges, but the limited (but more expensive) storage is a deal-breaker.
