One main purposes suggested by Nadella was that you could buy just a phone and have a desktop too for 3rd world countries where they cant afford both. But now we see that even the limited continuum desktop requires a flagship class 550 pound phone, and perhaps liquid cooling. Not to mention you need a monitor, mouse, keyboard and $100 adapter box. The poor might be better served by something like a Moto E and a chromebook for a lot less. Sure you could suggest "in the future" is the goal but even then how useful is a phone as a desktop, really. It will never be a true windows desktop and at best be a very poor one, besides the initial novelty trick, but then easilly ends up dropped in the crapper losing all your files. Even a $30 chromecast or hdmi link from an android smartphone can give a useable "desktop" if that's what you think you really need.
