If all you need is minimalist protection for the iPad's back, this clear plastic snap-on case could help. But fuller protection is available.
Newer Technology's NuGuard Clear case isn't an iPad sleeve, and it certainly isn't an iPad bag. Rather, it's a clear, rigid, polycarbonate shell that snaps snugly onto the back of your tablet. As such, it will keep that back scratch- and grime-free and provide some protection if you happen to drop the tablet on its backside. The clear plastic case does nothing to hide—or to soften—the iPad's metallic look, but it does provide a slightly better grip than the iPad's own aluminum back. Still, the NuGuard Clear doesn't completely solve the iPad's holdability problem, and it doesn't do anything to protect the screen, either. In other words, if you want minimal protection, the NuGuard Clear case might be worth considering. But if you want fuller protection, you need a fuller sleeve.
