So the entire industry is transitioning towards tablets and cell phones that can host a full desktop environment, and you're suggesting that they will just cash out and continue selling regular smartphones?
Apple has patents that predate Windows 8 and Ubuntu Mobile (unity 8 as a concept too?) for a universal touchscreen + desktop UI, that would mark the unification of OSX and iOS. The only reason they aren't making a move is because they know iOS is their golden boy, and making the move now would be self-cannibalism. Steve Jobs apparently pushed for the iPad to be a small mac rather than a large iphone, which makes absolute sense.
Someone needs to light a fire under their ass though, the most recent product cycle was mediocre. Hackintosh is the only option for anyone that actually wants an upgrade.
You'll find me first in line to buy such a device. Phones and tablets just don't fucking do anything.
