You could wrap your shiny new 'iThing' in bubble wrap to stop it getting scratched, but that might spoil its looks. Alternatively, you can get a similar effect with Ozaki's new range of Bubble Cases for iPhone/iPad.
They have a "semi-transparent jelly construction" apparently, and come with an iCoat screen protector plus cleaning cloth.
The Ozaki IC482 iCoat Bubble for the iPhone 4 costs £20, the IC832 for iPad £35. You can choose from clear or translucent black finishes.
