How much memory does a Xbox 360 Elite come with?

Also which xbox do you think is better the Xbox 360 250g slim or the Xbox 360 4g slim?How much memory does a Xbox 360 Elite come with?
The elite comes with an 120GB Hard drive. I also definitely think if you are buying one to go for the Xbox 260 250 GB slim. You will need more than 4GB of memory for you files and compared to the old ones you will same yourself $100 by not having to buy the wireless adapter as well (old ones don't have it). If you can get a good deal on the elite though go for it. 120 GB is a lot of space. I currently have the old 60 GB Xbox 360 and it works great.
