Maybe the H/W manufacturers need to look at setting up a consortium to deliver OSs for both PCs and phones that they can shape to what they perceive to be the market's needs.
They did. It was called Symbian, and was the most popular OS before Nokia made the "smart" move of taking over Symbian. Then all the smartphone manufacturers decided to flock somewhere else, and Android ended up being the replacement OS.
Even then, Symbian was moving into an interesting direction up until the Elopocalypse. Proof? Symbian Belle had rave reviews.
