The number of people in the business handing out CDs with pictures on them or using iPads to show their work like a portfolio is off the charts. When you sit down with a potential client and pullout a full sized print (13x19) portfolio with pictures that have that "3D" pop and clarity that people feel like they can step into, it can make a huge difference.
If you are just printing large to hang in you hall as casual art then I will agree. If you are competing for work against other talented photographers then the differences will be noticed and size matters. It is a hard business to separate yourself in and the differences between success and failure are often found in the margins.
Shooting in the music industry you will see hundreds of "friends of the band" photographers all trying to get published. It seems like everyone has a Canon 7D and the latest super-slow, super-soft, super-zoom. They dump JPEG loaded CDs on the desk of anyone who will give them the time. When you try to print their work at any decent size it starts to fall apart. The weakest link I see in most starting photographers system is their lens selection.
