The only difference is the hard drive size.
There is not really a big difference between the two the only difference is the 250GB has a way bigger memory than the 4GB and the 250GB is worth the money
One is 4GB and the other is 250GB.
The 250Gb Xbox 360 has ALOT more memory for saved items.
the slim is quieter, is smaller, has a different shape, a 250GB hard drive, and is ready for kinect.
The main difference is that the Xbox 250 GB holds much more memory than the GB..........and the 250 GB has a glossy cover(i_e the main Xbox's body) while the GB has carbon fiber on it
250gb if you can afford it, if you buy a 4gb you will need to buy a hard drive, A 4gb Xbox with a hard drive will probably cost more than a 250gb
The Xbox 360 Kinect comes with it.
yes
No, only the new 250gb xBox 360 does.
It is for an XBOX. You can buy an external hard disk, though.
No. The Xbox 360 S has built-in wifi.
250gb
