1200 lines feels cramped. That's the main reason I would consider a 30" LCD, but I think it's maybe too big and would have to think about the price. Someone should make a 26" 1920x1440 4:3 LCD monitor. That way, you can watch 1920x1080 content without rescaling (23.35"), plus it gives you a generally compelling reason to upgrade from 1600x1200: 240 extra lines. You would need dual-link DVI for just a little bit, so most people would just have to go through analog.
