Query: Convenient Stand, but a Little Slippery

The stand is sleek and convenient, but I have had the laptop slide off a few times (I use a 17" MacBook Pro). The key is to position the laptop on the stand with about an inch of the grippy pad on the top sticking out, so the weight is distributed onto the back of the stand more evenly. I definitely like the way the stand looks, but it is a bit pricey considering how simple a piece of "equipment" it is. Ask yourself if you wouldn't rather just stack up some books?
