And the turn your phone into a desktop computer has been tried before and failed.
As far as what the tech authors blog posts want I'm not sure they represent the average Apple consumer; although Apple isn't stupid and does seem to provide worthwhile updates with each release.
As far as the file system, I can almost bet it's not a windows free for all and those who don't want to use it can continue to use iOS as if there was no file system.
We'll see how Microsofts implementation goes, I'll bet it's a big hit. It won't be a huge system seller, but it will make money for MS like the surface pro's do. I'm not sure who else tried it and failed, Samsungs implementation isn't really the greatest. The power Microsoft has behind them is they have built a system where you can have major x86 programs run on a smartphone, they also have a framework where programs can turn into apps depending on if the phone is used as a phone or docked, and they've made great strides in making it easier for devs to port other mobile apps, and also x86 programs into the ecosystem. Once again I don't see it setting the world on fire, but I do see it being popular in the enterprise world and some in the consumer world and being valuable.
The file system, oh you can bet Apple will hamstring it and only open up things like media files and such. Still, it's an improvement over what was there before, but I'll bet it will still be a far cry from a real file system.
Tech authors I would say have the ears of many consumers. Take someone like Walt Mossberg, he's very popular and not just with tech enthusiasts. While I say that many Apple consumers are happy with simplicity, by the same token many many Apple consumers are also technically inclined and listen to the tech blogs. No Apple isn't stupid, but they do know how to do just the minimal amount of upgrades that consumers will feel deserve their money.
