Couldn't agree more with both points. Of course android ate Nokia's pie (cheap phones for everyone). Rather unsure about blackberry, i think thats more a thing that android and ios both now have excellent infrastructure integration (MS exchange etc) for corporate support.
You're also right with how cheap OEM android phones are taking over the market. iOS is losing marketshare pretty much everywhere where phones are not heavily subsidised or the comparative income is low, namely everywhere but the US and UK (and a couple of others). Unless apple drops its ios prices to more reasonable levels (they are really taking the p*ss), it's going to be the same story as the one that unfolded with mac/windows.
