Had a family friend over from the UK over the holidays. They have two daughters, 14 and 11. Every couple of days the Mum invades her eldest daughters privacy by scrolling through her phone when she is asleep to see what she has been up to, clearly concerned by what they can get up to and see. I explained WFI to her and she was ready to download and sign up right there and then, but i had to break the news she will have to wait for the international rollout unfortunately. Reaffirmed my view though that the market for this product is potentially enormous if they can get it out there.
