Even if I had an iPhone, I wouldn't use any of these services and would use cross-platforms alternatives instead, when possible.
Good luck getting family, friends and co-workers to use cross-platform alternatives when they're technically inept or apathetic. Then, the moment they F something up on their own device they start blaming you for installing Hangouts on their iPhone, as if that's the cause.
The first thing he did with it? Run minecraft with a visibility setting that ate up all 16GB of ram.
I find this comical, I've never played Minecraft but what I've seen of it looks like the graphics engine was borrowed from the original Castle Wolfenstein 3D. I would've never even thought the game was 64-bit and could address more than 4GB of RAM. From a quick Google search I see that it is Java-based and indeed capable of 64-bit addressing, what could it possibly be doing with that much RAM!?
Heuristics are bug ridden by definition. If they didn't have bugs, then they'd be algorithms.
