I think that among several other things, what strikes me most is that we are very close to achieving a 100% anonymous transaction, through an encrypted sms message, without being connected to the internet and soon on a non-smartphone.
You will can buy a $10 dumbphone make an anon payment and then throw this phone in the trash.
If this message is intercepted, the only thing that will appear will be you sending an encrypt text message, coins not appear.
Sorry for my English

EDIT: this will be very useful in countries that have authoritarian governments, without freedom as you can see in this video one transaction made in iran, where cryptocoins are prohibited:  http://www.liveleak.com/view?i=8b3_1410143623#mwveAQlT6xzBrA7K.99

"This will be the future for opressed countries and where governments cannot be trusted."

Think about several good possibilities. An international journalist will can pay securely his informants in countries at war or regions under the control of terrorists.
