As someone who wasn't familiar with saurik or his work before this original picture posting (sorry!), I'd just like to say that it's really refreshing to see such a level-headed member of the community at work. Some of the responses (on HN and other places) to his original post seemed very dismissive (along the lines of the now-famous "Yes, Glass is hackable. Duh."), which could easily lead to some defensive bickering. But from what I saw, saurik responded calmly and thoroughly to many comments, in situations where I've seen less experienced/matured members of the community (no, I'm not going to name names) take a... different approach. I'm looking forward to reading his write-up more thoroughly when I get the chance.
