If you have a Logitech Ultrathin Keyboard Cover for iPad you'll notice how easy the aluminum finish on the back can scratch and wished it had more grip aka rubber feet like the rubber pads/feet on any MacBook.
If you own a Rain Design mStand for your MacBook, take a look at he rubber pads on your mStand. Hmmmm. Turns out Rain Design sells replacement rubber feet which are perfect for applying on the aluminum back of your keyboard. No more slippery keyboard when typing!
