Software developers?
A large percentage of those developers would not have known the difference since these phones ran Android and the VM abstracted this away.
Only for games and some other apps that use the NDK would this have made a difference.
I don't understand this comment. Who is talking about when ARM was established?
Android runs on the vast majority of the world's smartphones and smart devices TODAY and was compatible with intel's(x86) mobile processor. That would have been enough of a market.
edit:// I am commenting on the ASUS ZenFone 2 which has the intel processor running ANDORID, fyi.
