Welcome.
"Smartphones vs Personal Computers" just about sums up my thoughts on that matter. Well said.
Sadly in a purely profit driven world, the practical solutions often fall by the wayside.
A toy/fashion accessory with firmware which can't be updated, once the vendor ends support, no option to change OS and which is made cheaply in the far east and sold in the west, with a huge margin, is always going be more profitable - especially with what amounts to planned obsolescence as standard.
