Yes, you're right the world is going mobile and in mobile less (no) moving parts is better (more durable etc.)
That is also why I think that consumer grade devices will be unlikely (unless read speeds are bumped up, too)
But mobile, in our case, means also a shift to the cloud, where significant more potent storage technologies could make a real difference.
I really hope, too, that technology will lead to something new.
Fair enough. It's hard to see where these kinds of write (but normal read) speeds would be necessary, even in a server farm, but I guess the beauty of enabling technologies is that they allow for use cases no one could have imagined when they were conceived.
