For the past five years, industry observers and IT professionals watched as notebooks have taken bigger chunks of the PC market, with corporate users and consumers looking for increased mobility and flexibility in their PCs and turning away from the traditional desktops that once permeated the desk and cubicles of enterprises for years.

However, it seems that 2007 could be the year that notebooks, more than desktops, become the bigger revenue generator for major PC makers like Hewlett-Packard, Dell and Lenovo.
