I don't know whether the 29$ price tag (even when compared to other similar Nokias already in the market) is all that revolutionary but they certainly have pitched their product perfectly:
"or as a secondary phone for just about anyone... has the same durable build quality you’ve learned to rely on over the years... stand-by time of up to 29 days"
After Microsoft claimed to have banished the 'Nokia' name forever, they now evoking imaging from Nokia's days of glory. Of course, the question now on every Indian's mind is - Can the Nokia 215 hold a candle to the legendary 1100?
