Abandon ship!
Microsoft's big relaunch seems to have been inspired by $9.3bn of out of touch research, which no one dares challenge.
The PC as a device for the consumption of media, has been destined to become more portable ever since the phone. Unfortunately for MS they released the equivalent of the first analogs, massive, impractical and expensive. Nokia were initially great, one of the first to have introduce a camera, gps maps, video calling, downloadable apps, etc. But their implementation stagnanted and Apple took the lead.
Microsoft wants to get back into this game, home pcs will be marginalized at an ever increasing rate, and so will their profits.
The problem is they are panicing, rather than innovate and take portable media to a new level, they are using their remaining assets as collateral.
I'm willing to accept a fair amount of business use is media consumption, but not all, and certainly not for the folks creating the media, or maintaining the backend systems. By forcing unproductive elements of Metro upon them, it makes it far less painful for them to switch to other platforms.
It's probably too late to make Metro disruptive enough to succeed, so the only thing the shareholders can hope for is a quick fail, and reconciliation as a smaller, business oriented, service provider.
