Um, no. I won't install the facebook app for example because I don't want facebook to access my SMS, location, decide to pop up annoying notifications on my phone that may or may not be able to be disabled, perhaps poll in the background, etc.

I don't want to INSTALL every website I visit onto my device. I want to consume the content in a sandbox and just be able to leave. I could understand say if there was an actual need, like I have one to automatically upload photos to flickr, but WebMD? McDonalds? A site I visited once two years ago?
