I've been toying with the idea of buying an arcade version 360 from Sainsburys while they're so cheap so I can have one upstairs and one downstairs. The only thing is, I can't seem to find any info about whether or not I can simply unplug the hard drive from my Elite and plug it into the Arcade when I want to use it upstairs. So what's the verdict? If I have two consoles, can I swap one hard drive between the two and use my DLC and saves, etc.?
