We are still awaiting the numbers from Amazon and Barnes & Noble about eBook and eReader sales over the holiday weekend, but we have learned that overall e-commerce sales were up this Christmas.

According to a report from IBM, which tracks 500 e-commerce sites not including Amazon, online shopping was 16.4 percent higher on Christmas Day 2011 than last year.

The Associated Press has more about the report: “It found a huge increase in the number of shoppers making their purchases with iPhones, iPads and Android-powered mobile devices. In fact, nearly 7 percent of all online purchases were made using iPads, just 18 months after the tablet computers were released by Apple Inc., said John Squire, chief strategy officer for IBM’s Smarter Commerce unit.”
