Time will tell if Apple has actually done what the said they've done. They still could have a copy of the decryption key on their "lawful access" servers and only provide the access to the US intelligence agencies. (that, at least, would keep our "trusted" allies from leaking the information *cough* France *cough*).
Me, I really don't care if law enforcement can gain access to my devices - nothing to hide - and I'm not a conspiracy nut.
(and I also invested just over 8 years of my life at BlackBerry - where we did exactly that for law enforcement).
