Yeah, even if the iPad is literally paper thin, we would still add the thickness back to what it once was by using a case. Or in that case, a folder? Hard to understand.
I don't use a case on my iPad.
A skin works well in making it less slippery.and less slippery.
I don't pay for an iPad because it's super thin. I pay because it offers the best user experience on a tablet.
With iPad most cases help prop the device up to make media consumption more comfortable. Hard to avoid as the device doesn’t have a kickstand.
