It is your opinion. I think it is crazy to have multi-core smartphones (even quad core @ 1,5 GHz) without multitasking.
It is impressive how Apple, Google and Microsoft can change people minds so that dumbed down (mobile OS) are accepted without real multitasking, open Bluetooth, screenshot capability, USB, microSD, offline maps, etc.
I own a Asus Transformer TF-101, IMHO Android 3.x/4.x is indeed a dumbed down OS. Wasting good hardware.
