You can store around one year of moderate quality video/audio, (by which, I guess, I mean fairly low quality by today's standards) and GPS location, in just ten terabytes. Trigger high quality only for stuff you're really interested in, and a few very high quality still shots and you can probably still squeeze in a year of recording in only a bit more than that. Call it eleven terabytes.
Add a video search and you'd never be asking "now where did I leave my keys?" Or, rather, you'd be asking, and your AI assistant would do a quick video search of the past few hours, and tell you "you left them locked in the car. Again." (my AI assistant would be snide, sarcastic, and treat me with a combination of difference and thinly veiled contempt; because I think it'd be fun, that's why. Ideally I'd license Jeremy Irons' voice for my AI assistant.)
Of course there's a whole raft of legal/moral/ethical/privacy problems associated with that, but assuming Moore's law holds steady we ought to be seeing 10TB of portable storage costing only around $10 or so by 2018. Our lives will be recorded, the only real question is: by us, or by a panopticon state? Again, I argue that David Brin's "Transparent Society" is well worth the read.
Storing all sensory input would be interesting, and likely take a lot more storage. But I doubt we'll be seeing that available (at least to the general public) in ten years.
Here we see an interesting new strategy: the carefully timed retraction. FoxNews has recently began posting stories containing false information about John Kerry. The first was the story containing made up quotes intended to make Kerry look effeminant [1]. The second was a story in which they quoted the anti-Kerry group "Communists For Kerry" as if they were a genuine pro-Kerry group. When they quoted Billionares for Bush they made it quite clear that they were an anti-Bush group.
