Despite the hype, and hope, around the launch of Windows 8, the new operating system did little to boost holiday sales or improve the year-long Windows notebook sales decline, according to the NPD group.

Windows notebook holiday unit sales dropped 11 percent, on par with Black Friday, and similar to the yearly trend, but revenue trends weakened since Black Friday to end the holiday period down 10.5 percent, the NPD's analysis showed.

ASPs rose only $2 to $420. Touchscreen notebooks were 4.5 percent of Windows 8 sales with ASPs around $700. Sales of Windows notebooks under $500 fell by 16 percent while notebooks priced above $500 increased 4 percent. Macbook sales dropped 6 percent while the ASPs rose almost $100 to $1419.
