Have you ever tried to explain to someone who is not an engineer what the relationship between 'a phone' and 'Android' is? Coincidentally I've tried twice over the last 3 weeks - both times concluded, after 15 minutes, with them concluding 'oh, so it doesn't matter much, right, all phones have it, it's just different between different phones'. Eh... yes, I suppose...
