Search the play store for an app called "permissions free". It can enable and disable permissions for any app on any ROM as long as you're rooted. I use it extensively.
Or buy from a company that allows you to customize every aspect of the laptop. I have an Eurocom Racer http://web.eurocom.com/EC/ec_model_config1%281,219,0%29 with Radeon HD6970M graphics. You almost can't get better non-Nvidia mobile graphics than that. Got it with no OS installed, and it runs xubuntu like a champ.
I have, and they're not acceptable.
The upcoming Star Citizen will have full support for the Rift.
They're aimed at different (yet in some areas common) consumers. The Rift is for gamers, to provide a completely artificial replacement of the surroundings (virtual reality). Think Star Trek holodecks.
But at least the revolution will be televised!
Can't wait until I get mine.
