Windows 7 Launch Increased Software Box Sales by 234 Percent, But Hardware Sales saw Just 49 Percent Increase

According to NPD’s weekly tracking service, Windows 7 software unit sales in the US were 234 percent higher than Vista’s first few days of sales. However, revenue growth wasn’t as strong as Vista release. Also PC hardware sales showed only a modest increase at 49 percent in year-over-year sales and 95 percent over the week prior to launch.  Vista on the other hand had 68 percent rise in sales over the prior year and 170 percent over the week preceding the launch.
