If they make an Atom based phone that is running a full or mostly full version of Windows (not the semi crippled ARM port) as is current rumor, a "Surface Phone" so to speak, then that changes the game a LOT, suddenly app support is a non-issue for a bunch of things, I'm not talking about running full desktop apps on a comparatively tiny screen, but things that are sorely lacking on ARM Winphone like third party VPN clients, corporate asset management agents, in house developed (generally crappy and poorly maintained) apps, etc. Add some sort of dock or remote display capability then you have a laptop replacement for many mobile users.
