Gamespot.com is saying that if your not dong get the $400 system, then your not getting a real Xbox360. Which, I agree. I think the core system is a waste.

"Paying $400 for a gaming console is undoubtedly a lot of scratch, I'll grant you that. But listen up--if you're not shelling out that extra Benjamin for the $399 console bundle, you're not getting the real Xbox 360. In fact, I daresay you're getting ripped off. Nearly every accessory included with the $399 bundle is hardwired to MS's vision of the next-generation console: the wireless controller (as opposed to the Core bundle's wired version), the 20GB hard drive (which should never have been separated in the first place), the component HD cable, the Ethernet cable, the Xbox 360 headset, and even the media remote control. Even if you don't have an HD-compliant TV or if you lack high-speed Internet in your home, chances are you'll benefit from one or more of the other accessories found in this bundle.
Face it, as a Core system owner, sooner or later you're going to want to take your 360 online and find out what the next generation of Xbox Live is like on your brand-new headset. Even though microtransactions don't sound that much different to me than, say, paying for course downloads in Links or new tracks in a Project Gotham Racing game, you'll still need somewhere to save all that extra data you went to the trouble to pay for.
And the 20GB hard drive will be your best friend when that time comes. As far as I'm concerned, several accessories in the $399 bundle--the headset, the hard drive, and the wireless controller--aren't optional in 2005; they're an essential part of today's gaming landscape. Bought separately, that trio of hardware will run you around $170. You do the math." - Brian Ekberg/Sports Editor
