A laptop is a small/portable computer.
Laptops typically may be powered either by batteries or by mains/grid electricity where available.
Laptops are commonly connected to the Internet, where possible, through wired or wireless connections.
Laptop-type portable computers have the potential to greatly increase knowledge and communications for people in all areas of the world.
Following "Moore's Law"W, the price of laptop computers has continually decreased and their power increased. It is now becoming possible to visualize laptop-type computers cheap enough to be available to poor people in both developing and developed countries. (For example, the One Laptop Per Child / OLPC project.)
Additionally, reduced size and expense of computer components is resulting in a merger of computer and cellular phone technologies ("smart phones", from fairly basic models through the iPhoneW (TM) from Apple, Inc (TM), the N95 from Nokia Corporation (TM), or the 8525 from AT&T Mobility (TM)(formerly Cingular).

Environmental impact of laptop production and disposal is a concern.
