that arcade deal from dell is nice, but I think that version now has the 256 mb of memory on board instead of the stick. one of the reasons for getting the arcade was for the memory stick so I could transfer stuff between harddrives (I got a 2nd hand 120 gig), so that is a bit of a bummer.
actually, if I do get that one, whats the cheapest way to get a memory stick for the 360?
