This device is being marketed to the internet neophytes. So here's a crazy idea! (Speaking as someone with NO idea how the device functions, assumptions FTW)
Instead of saying "Here's the internet in all it's wonder go play" to your bewildered target audience. How about doing a (I can't believe I am about to type this) AOL content portal type effort?
You'll have content that is filtered removing the traps of the internet, if you've ever had to educate a grand patental unit about the internet you'll know what I'm reffering to.
Content providers could purchase premium advertising space, and with some smart market studies, target the right users.
Educational content for the youngsters, Access to Banking Sites, Goverment Sites (the few that haven't been hacked).
All of the traffic in this zone should be gratis, as if it is done right MTN could do this and turn a profit. While getting a warm fuzzy feeling of not completely rodgering their consumer.
Still offer the big bad scary internet (besides if you're using this forum you'd easily be able to google a guide to "root"-ing your Spectrum.. ahem InternetOnTV hardware), but at least give the consumer something to do with this piece of hardware before it becomes another piece of junk cluttering the lounge.
