Kid expert here. I've got 6, 9, and 11 year olds all of whom have iPod Touch's for more than a year and are always begging for dad's iPhone when we're in restaurants.
I can go on for several paragraphs or just cut to the chase: You want a Belkin Grip Vue. That's it. Extra grip, complete back/edge protection, a bit of a rubbery bounce if it ever drops.
As far as screen protection goes, skip it. My kids are not very careful with their iTouch's and we've never,
ever had a single screen scratch on a single one and we're talking dirty sandy hands from the beach, sticky hands from Fruit Rollup's, iPod's that fell in the crack of the sofa, you name it. There's a video on YouTube showing some guys trying to scratch the iPad's screen with rusty nails and the thing is impervious.
Belkin Grip Vue, problem solved.
I'm working on a theory that I can stuff an iPad with the Belkin Grip Vue into a Griffin Elan Passport pleather folio so I can have the best of both worlds which is:
1. Grip Vue protection for the kids.
2. Pleather folio style for executive dad.
3. Never having to take the Grip Vue off the iPad in the process.
I'll let you know how that goes. In the mean time, get to an Apple store and buy a Belkin Grip Vue.
