Why is the Wii's pointing system more practical? It's less accurate and still requires a device placed above or below your display.
if you noticed, so does the PS3's wand, you know, the camera on top of the TV. you see, the Wiimote acts similarly to a lightgun in that it recognizes points of light/color and can act upon them. because of modern TVs, lightguns don't work so well, thus Nintendo implemented a modular system that worked on the same principle as arcade shooters with LCD screens: they used opposed infrared lights to determine position and distance from the television. thus, using these lights as a guideline, a programmer can put in the parameters of the screen he's working with. this is modular and scalable by TV size and sitting distance by adjusting sensitivity.
the PS3 wand on the other hand does that all backwards. sure, it's able to calculate the absolute position of the wand in space with the camera, and the accelerometer and gyroscope do the part of calculating the objects orientation in space, but BOTH of these parameters must be used in conjunction in order to get accurate results in pointing, while the Wii only uses one set. this is a problem because the accelerometer and the gyroscope can be fooled by movement that's too rapid or sharp, and thus must be carefully programmed to keep out the noise. theoretically, it can work just as well as the Wii pointer, practically however, is another issue.
both systems suffer from the same lighting problems as they're both IR systems, but the Wii's system for pointing is ideal as it focuses on a more reliable and simpler system, one that's been used for YEARS.
Furthermore, the DS3 is at least wireless. Having the Wii-mote and nunchuck tethered together is not a positive thing.
now you're just grasping at straws. that boils down to practicality on the manufacturing and consumer side. it's easier and cheaper to make the nunchuck tethered to the Wii than to dedicate extra cost and weight to a bluetooth radio and battery pack for both parties. that's to say nothing of the potential controller latency. it's more beneficial to me to have a wired nunchuck, and few would see the tethering of the two as bothersome. the awkward handling of holding a controller designed for two hands in one on the other hand, is far more problematic.
