[quote name='EasyTarget82']I was reading through the reviews and one guy has a point if your wanting a specific arcade. This has the listing for 256mb storage. So it's not the newest arcade model and no telling what chipset it is. If anyone cares.
edit: It's their only listing for the arcade so I'm not sure if they even stock the 512mb or if you could take a chance and end up with one anyway.[/QUOTE]
The odds are pretty good that you'll get a 512 unit, since those have been standard for since mid/summer 2009, although the packaging may not reflect this...I picked up an arcade in Nov (build date in Aug 09) and while the box said it was 256MB, it was actually 512 (although the actual usable memory space was something like 320mb because it reserves some of the memory space for avatar storage and a few other things)
