Creative's Zii Egg is an HD media player with enhanced 3D graphics and video acceleration that is positioned to compete with the iPod Touch. It is currently available for pre-order at $399 (and targeted at developers). For that price, you get 32 Gigs of internal memory as well as the SDK.
According to the Egg's homepage, you can add another 32 GB of SDHC storage, giving this thing a 64 Gigs for your media. It's got a capacitive, 3.5?, 320x480 multi-touch display, and can output 1080 progressive HD to your television. GPS (with 3D Navigation), accelerometer, and a special version of Android are also on the menu.
The device is just as much about the Plaszma platform/OS as it is about Android, and will not ship with Google's OS installed. However, a special version of Android will be available for download after these things ship in the second half of August.
