Logitech has a wide range of lapdesks to make it easier and more comfortable to use a laptop actually on your lap. They are nice because they keep you from roasting your chestnuts from the heat some notebooks produce during operation.
A new offering has been added to the line by Logitech called the Logitech Speaker Lapdesk N550. As the name implies, the lapdesk has speakers built-in that allows you to get better sound from the thing while it keeps the heat off your body. The N550 has a pair of stereo speakers and to power the speakers and get audio connectivity needs only one USB cable.
The N550 has a 4-layer heat shield design combined with soft air-mesh fabric. The desk places the speakers to each side of the notebook so the sound can be heard clearer. Pricing and availability are unknown right now.
