I'm not really sure what to think of this but to be honest I don't think it really matters unless one day I decide, need or happen to pick up an Arcade version of the Xbox 360. Aside from now having the long awaited Jasper chipsets, cross your fingers and kiss that RROD epidemic goodbye, the new Arcade units will also include 256 MB of internal flash memory. No more need for external memory cards, that is unless you're one of them nomad gamers who's constantly over at a friends house and use you're memory card to take you're gamertag and saved games with you. I'm not sure if it's Microsoft plan to make people buy more memory units or if it really is a simply a good gesture on their part. I personally have been wanting to pick up an external memory card simply to have as a back up of my game saves. These days, game saves get corrupt quick and those 30 hours you spent roaming the nuclear wasteland can be wiped by the game itself due to simple bugs. I just can't justify the price when I can get a more useful peripheral or even nourishment. it's a hefty price to pay for peace of mind. If you're gonna steal my Xbox 360 fine, just let me keep my hard drive. So there you go. Anyone picking up an Xbox 360 Arcade? if you are, and want to make sure you get one of the new units, just look on the box and the power rating should be 150W instead of the usual 175W.
