If you haven't seen it yet, this video has been making its way around the InterBloggaTwittersphere today:Short of making the cardboard frame yourself and purchasing an iPhone to slip inside, we're not quite there in terms of this capability on the current eReaders, but this video does suggest some wild possibilities, no?We're raising children who are obviously comfortable with the ever-adapting technology, sometimes more so than their parents. So why wouldn't something like this work? Can you envision a model you'd be willing to pay for? Perhaps purchase the dedicated device (or an app for the iPhone) and then pay for each new title? Interesting possibilities, for sure.(Thanks to @mitaliperkins for the link)
