What Us The Difference Between Regular Xbox 360 And Xbox 360 Arcade?

first off really no xbox called xbox 360
there xbox….arcade
xbox….pro
xbox…..elite
xbox arcade is just a system all white wireless controller and memory card that only holds 258mb~ btw this sucks u wont be able download nothi on market place no points in buying games with extra stuff because u cant download what u paid for. your so limited and if u get xbox live or even hooked up to internet for silver promise u download some demos thjere aleast 70 then over 100 arcade demos then there some games that as free maps and they require u to have them to play in there online
arcades are rip offs with hidden fees be the time u deside u want hard drive u force to buy the only one in stores which cost 180 bucks then u need headset for online and thats a lest 20 bucks u should just got your self elite then in feature when new system comes out u sell it for new system and u be getting less because u have to sell it in parts
then you got your self a pro thats 60gb comes with a white system with chrome on the dvd drive wireless controller 6ft Ethernet cable somewhat useless and a headset
then u got your self elite thats 120gbs black system blk controller 6 ft Ethernet cable headset
pick up elite or a pro or u regret it
