Simple mobiles

Vodafone have come up with the idea of a "simple" mobile, intended presumably for those far off on the left hand side of the technology adoption bell curve (e.g. ones parents).

However, their idea of a simple mobile phone looks more like a 5 year old standard mobe than the elegant simple device you might have hoped for.

My concept for a simple phone would be:
- one line display for the number, big green light to indicate you have a signal.
- 12 buttons, 0-9 plus Send and Hangup
- no text, phone book (maybe make the phone out of some sort of wipe-clean material so you can write numbers on with a pencil)

Or even:
- no number display, tone feedback as you dial
- flip open to pickup/start dialing and hangup
- automated end of number detection, like a PSTN exchange does (I assume the data is there to know that a number starting 09 has 9 digits, 004420 has 14, etc)

Or even:
- no buttons, just a flip.
- on opening the phone you get connected to an operator, who asks who you want and puts you through

These phones could even become fogey fashion items through their elegant simplicity (not to mention small size...)
