Features added to the microwave:

• Re-designed touchpad
• Nicer sounds
• Clock is automatically updated from the internet
• Can be controlled with voice commands
• Can use a barcode scanner to look up cooking instructions from an online database
• The microwave has a web page so you can control it from your phone (why not), and set up cooking instructions for products
• Tweets after it’s finished cooking something

I think this might be the most ambitious Raspberry Pi project I've ever seen.
