Lexmark has been offering its US-made notebook and subnotebook computers on the OEM market since 1991, but is now offering them direct to end-users from its Lexington, Kentucky factory. It is to sell multiple configurations of three different systems with factory-direct prices from $750 to $3,900, all under the Lexmark Lexbook logo.
