of course you can use with arcade,pro,and elite! (:
Arcade? Probably not.
yes I've got an arcade and xbox live works fine
yes
yes, i use a 360 arcade and it works perfactly!
No, any HDMI cable will work.
Yes you can, the xbox arcade is just an xbox 360 pro, without the hard drive in the box.
yes you can use the xbox 360 controllers on the xbox 360 slim. I use my controllers from my old xbox on my new 360 slim.
All Xbox 360's are basically designed to use a hard drive, so an arcade version can definitely use a 20 Gig hard drive, but if you may have to recover your gamertag.
There is no such thing as a corded xbox 360, all 360 can use wireless controllers, even the arcade unit.
Old gen Xbox elite yes and I think for the Xbox s is well
yes you can use any hdd for any xbox if you want something with less gb get a memory card
they are all the same they just have different hard drives Xbox arcade has no hard drive so you use memory sticks Xbox 360 has a average hard drive Xbox 360 Elite has a MASSIVE hard drive that can hold videos, pictures, save files, etc except they MIGHT have come out on diffenrt dates and my ges is elite
