Minimum Spec for Windows Phone 7 Devices

Windows Phone 7 is set to reach shops soon, but what's the minimum spec we can expect from a phone running WP7?

Sources have confirmed the following to be the minimum specifications, which as you can see would make even the base models pretty decent phones.

2 screen sizes: 480×800 WVGA, 480×320 HVGA
Camera: 5 megapixels or more, Camera  with a flash and seperate camera button
Processor: ARMv7 Cortex/Scorpion or better
Memory: 256 MB, 8 GB Flash or more
GPU: DirectX 9 acceleration
Sensors: A-GPS, Accelerometer, Compass, Light, Proximity
Multimedia: Common detailed specs, Codec acceleration
Capacitive Touch: 4 or more contact points
Hardware Buttons: Must be fixed on the face
Keyboard: Optional

We especially like the separate camera button, so many times have we fiddled around with passcode locks, only to miss the occasion we wanted to take a snap of!
