Xbox s has wifi adapter in it the normal one you have to buy one to use wireless
Xbox 360s Is the slim version.

Xbox, Xbox 360, and Xbox 360 Slim(the newest one)
The new Xbox 360 S.
On the older Xbox 360's, at the top. The Xbox 360 S, the hard drive is located at the bottom of the Xbox.
no it wasn't. Xbox > xbox 360 > xbox one
S stands for slim. AKA Xbox 360 Slim. The slim has many new features. Look it up.
you can use kinect on any xbox 360 including and arcade but you need to plug in kinect to a mains plug not the xbox you only plug in kinect to the xbox 360 s because it has a plug for it so don't worry if you think you need to buy a new xbox 360 s for kinect you don't the only reason they brought out the xbox 360 s is like the PlayStation (Sony) make the ps3 slim it's just the same with the xbox 360 s it's just smaller with a built in hard drive and built in wireless other than that there is no difference.
No. The Xbox 360 S has built-in wifi.
Yes, it was made for the Xbox 360 and the Xbox S system.
