The Rosetta emulation is supposed to be pretty fast. I have read stories about how sluggish Photoshop is under it although I don't use Photoshop. Vectorworks is supposed to be sluggish, but compared to the 500MHz G4 PowerBook I replaced it is blazingly fast. I am looking forward to the day SMAART, Vectorworks, MS Office, and Filemaker all go native. Those, Safari, and iTunes are the big apps for me. I run Studio Manager on the Toshiba, the PM1D is Windows only, and the PM5D uses a PCMCIA card which the Mac Book Pro doesn't have. I'm always going to want 2 laptops with me anyway so I can surf while I am running show music on iTunes.
