Podcast: Motion controllers

My podcast is about the three main home consoles, but instead of focusing on their hardware or software, it will be focused on their motion controllers.
My group consists on three people, me, José and Flávio, each one talking about one motion controller (for PS3, Xbox 360 and Wii).
We'll start with an intro, then each one of us will talk about one controller: what they do, why they are different, why they might work, or not. This will be followed by a conclusion where you can find a face-off and talk about the pros and cons of each one of them.
My part will be about the PS3's Move and it's sub-controller(see above picture).

This is what i found about it. It was taken from some websites, plus what i already knew about it.

Playstation Move:

PlayStation Move is slated for worldwide release by this year’s fall. Hardware available at launch includes the main PlayStation Move motion controller, and an optional PlayStation Move navigation controller. It will compete with the Project Natal and Wii Remote motion control systems for the Xbox 360 and Wii consoles, respectively.
If you've seen a Wii before, you're already familiar with the most basic concept here. PlayStation Move is a motion controller system, with sensors to detect the player's movements and translate them into gameplay.
Where Move departs from the Wii is that while the Wii has detection of movement, pointing, or even exact orientation, Move can track its controller precisely within real 3D space, instead of just relative movement based on a previous position. Most gameplay motions require a full and complete movement on Move -- but it also means interesting things for augmented reality. Of course, for augmented reality you need a camera, and lucky for Sony it has the PlayStation Eye already on the market. In fact, the Move system is partly based on what the Eye can detect of those colored balls at the end of each Move controller, which lets the PlayStation know how far away from the camera the controller is, and map, a tennis racket exactly to a user's hand, just to give an example.

All of this would be worthless if Sony hadn't worked out the potential lag in such a CPU-heavy tracking process. They say they've got the problem cracked, sending control data with a mere 1 frame per second delay -- equal to that of the DualShock 3.
Other huge differences between the Wii motion controllers and Move is that Move has less buttons then the Wii controller, making it less confusing for new players. Move is powered by rechargeable batteries like the Dualshock controller, unlike the Wii remote controller which uses AA batteries.
Wii is also known for losing track of your movements easily, something that doesn’t happen with Move. The Wii remote and it’s subcontroller are united with a short cable, something that Move and it’s subcontroler don’t have, making your movements much more free. Move is also much more accurate with your moves then the Wii motion controller, making it easier to handle.
