The move to mobility continued to be a key factor during this year's back-to-school season (BTS) one market research firm indicates.

Notebooks accounting for 64 percent of all personal computers sold in United States through the BTS season, researchers at Current Analysis found. This represents a 46 percent growth from the 2005 BTS season.

Notebook pricing clearly played a role in the increase, the firm stated, with the average selling price of the portable computers declining 23 percent compared to the previous year. Average prices hit significantly below the $900 marker at $839.

In contrast, desktop sales saw a unit sales decline, falling 2 percent from the previous year. The decline reversed the positive trend of the previous year, dropping desktop revenue 18 percent.

The firm defines this years back-to-school season as the period spanning from July 16 through September 9.
