From Kotaku:

• Touch Sensitive Buttons – turn the Xbox 360 on or off and eject a disc with the swipe of a finger
• Whisper Quiet – Whether you’re playing a DVD disc or from the hard drive or navigating the dashboard, with the all-new and much quieter Xbox 360, the only noise you’ll hear is your own laughing, cheering and playing
• Wi-Fi – Built-in 802.11n Wi-Fi for fast, easy connection to your friends and entertainment on Xbox LIVE.
• Hard Drive – 250GB internal, swappable hard drive for even more storage. To access, remove the bottom panel by pushing the small tab toward the front of the console.
• Kinect-ready – Custom Kinect port on the back of the console that directly hooks up to the Kinect sensor for controller-free fun.
• USB Slots – Five USB ports, three in the back and two in the front.
• Power Supply – Smaller and more efficient. Xbox 360 250GB and Xbox 360 Original power supplies are not interchangeable.
• Wireless Controller – The award-winning Xbox 360 Wireless Controller matches the console in all black with color-matched thumbsticks and directional pad with a touch of gloss and chrome to complete the look.

This game is easy, complete it on normal and hard whilst collecting all the secret eggs and the 1000Gs are yours.

At the moment on this game there are so many bugs and glitches. Its annoying. Here is the achievement that glitched out for me:
Pandora-dog Millionaire (50G) – Earn $1,000,000.

Apparently starting the game again will fix the glitch and the achievemtn will unlock. Yay!
