A netbook is a small laptop computer designed for wireless communication and access to the Internet.[1] Walt Mossberg calls them a "relatively new category of small, light, minimalist and cheap laptops." [2]
A netbook omits the laptop's optical drive and often its ethernet port because netbooks are optimized for size, weight, and cost. The USB port still serves as a (non-wireless) way to load software or to interface hardware like an external drive or a camcorder. A netbook cannot yet easily substitute for a laptop in cases where more power and ports are recommended; for example, to edit a video, and make a presentation with it[citation needed].
