You've spent a couple hundred bucks on a great shiny office desk and a few thousand more on that heavy new iMac set on top. It's a worthwhile investment to spend a small fraction more on a secure guard to protect them both from unnecessary scratches. But the good news is, you don't have to.
Hard Graft's iMac Slipper is a wool-and-leather shoe that fits over your iMac's foot, Cinderella style. Hard Graft is known for their hardcore and high-style gear bags, so this slipper is no doubt a great buy for anyone who wants a custom-fit cover that keeps their iMac (and desk) scratch-free while you're sliding it around.
If you want to get the same features and save $40 in your iPad fund at the same time, just grab a $5 (or less!) pack of felt furniture pads. They'll give you the same ease-of-movement and protection from desk scratches without the high price tag. We like these large, square felt blanket pads from Waxman.
