If you use your laptop on the couch, or in bed, laptop-desks stop it sliding around, or warming up your nether region. And while we like Logitech's Comfort Lapdesk, the new N315 adds a mouse-rest—pretty good for $30.
The washable, anti-slip top has room for notebooks with screens 15.6-inches or less, but definitely isn't as padded underneath as the $40 "Comfort" model. Still, the N315 is thin enough to fit into a laptop sleeve.
Companies like Belkin and Levenger also make decent laptop-desks, but the N315's retractable mousepad and portability are a good twist. Even if it does kinda look like a fast food tray... [Logitech]
