Twelve South GhostStand
The GhostStand ($34.99) by Twelve South is a transparent, modern platform designed to elevate a laptop to a comfortable viewing angle. Though designed specifically for the MacBook, it should work well with practically any laptop on the market. The GhostStand's silicone rails serve a dual purpose: keeping your laptop in position on the stand and the stand in position on your desk.
The GhostStand ships as two pieces of clear, acrylic plastic. Simple assembly is required. Once in place, though, Twelve South discourages disassembling the stand.
