The company will be focusing instead on smaller and newer form factors. For one, it will be working on its Next Unit of Computing (NUC) boards, which are 4" by 4" and intended to be a self-contained PC. Legacy support for old motherboards and the new Haswell motherboards will continue through their respective warranty periods. 'Given the competitive landscape, it’s not a big surprise that Intel is refocusing its efforts on areas that have greater potential impact on future growth. All segments of the PC business are under extreme pressure, with sales slipping and users gravitating toward tablets and smart phones. Focusing on reference designs for all-in-one PCs, Ultrabooks and tablets will enable Intel’s partners to more rapidly ship products that appeal to the new generation of mobile users.' AnandTech points out that one of the reasons Intel put out motherboards for so long was to assure a baseline level of quality for its CPUs. Now that the boards coming out of Taiwan are of good quality, Intel doesn't need to expend the effort.
