Shame. Was hoping to try it out some some time. Won't be happening now.
Let's just be clear: I agree with the basic argument of the article: backers of Kickstarter projects are not equity holders. They don't actually get a say. The Oculus guys can sell out to whoever they want, without having to be held accountable to their backers.
Just don't go shitting on guys like Notch voicing their opinions saying, "fuck it, I'm out, this is bullshit".
Rooting means unlocking the OS so that you attain Superuser status. I.e. it allows you to findle with things you probably souldn't be fiddleing with, unless you really know what you doing. Most people do it so they can install other versions of the Android OS and to run apps that have functions that require the app get Superuser privileges to work.
Most of the time you would have to unlock the phone at the hardware level to do this (a process that is a lot more complicated and different on nearly every phone), but the Nexes phones come pre-unlocked. So it's just a matter of flipping a switch in a menu or installing a Superuser app.
In short unless you know you need it, don't bother. But if you do decide down the line (after reading up on the subject) to root/install another AOS/fiddle around, the Nexus phones are the path of least resistance. Also no crappy bloatware!
Yeah, if you're used to playing these sort of games games Hard mode is the place to start. Unlike some games *chough*DmC*chough* you don't have to play through once just to get a fairly challenging difficulty mode.
You could also use the Konami code to unlock all the difficulty modes from the start if you wanted...
