Last non-Smartphone sold on ...

2003: Dell, Inc. no longer includes floppy on their home computers.
2007: Last CRT television set sold by UK DSG (Dixons).
2008: Last standalone JVC VHS-only unit was produced.
20XX: Last non-Smartphone mobile phone is produced.

So, when do you think we will see the end of "dumb" mobile phones? I think 2014 - am I overly optimistic in my estimate?
