Once again, this is an understood limitation of TN panel technology. Every LCD display is gonna look poor in one way or another when you view it from outside its rated viewing angle; and the viewing angle of TN laptop panels is usually more narrow than most. It is not an MacBook Pro problem. It is not an Apple problem. It is a well-documented, well-known, industry-wide issue.
The only thing unique to the MacBook Pro is that the new LED backlight causes a color shift towards yellow when you view it from the sides. A typical CCFL display might shift towards blue or magenta instead, but it will shift. Some might even do a complete inversion of the display's colors or otherwise lose all sense of contrast.
Another thing is that the yellow shift is greatly exaggerated by the default ColorSync profile shipped by Apple. The calibrated display in my MBP has only a hint of a yellow shift from the sides. Out of the box, it was far more obvious.
Unfortunately, we are stuck with these limitations for now. The other LCD technologies out there aren't available in panel sizes suitable for laptops. Furthermore, these alternative technologies usually consume more power, which makes them even more unsuitable for portable use.
If you feel these limitations are not acceptable, then you need to invest in desktop monitor that uses either PVA or IPS technology. Laptop displays have never been acceptable for color-critical or wide-angle viewing. Maybe that will change one day - but not this day.
