if you're worrying about the saving data memory, you should get an elite. other wise the premium is the best choice. Premium gives you a headset, HD. arcade its just the system that bundles with some arcade games.

u can only play some games on the arcade cause it is barely any memory on the arcade and some games have a memory limit that u need to save.. If u get the 20 gb (it's what i have.. and have for a year.. i only used up 2 gb) it's a fair amount of memory considering i dont download alot of stuff off of market place. i would just save up and buy the 60gb premium xbox if u are worried about memory and only 50 bucks more that the 20gb console

The 360 arcade can play all 360 games but none of the orginal xbox games as they would require a hard drive. You can save game data on the provided 256 MB memory card. Keep in mind that the arcade does not come with cable necessary to output in high-def, you would need to purchase the cable separately. 256MB would fill up quickly with game saves and any add-on game content such as purchased tracks for Guitar Hero 3. I would suggest going with the 60GB 360 as it comes with the HD cable and plenty of storage space.

nice question im wondering the same thing
