Apple's iDevice line is certainly doing its part to stimulate the economy. That's according to a new report from retail analysis firm RichRelevance.

Despite enduring a four year lul, eCommerce has picked up the slack and returned to levels of consumer engagement not seen since prior to the 2008 global economic meltdown. In fact, comScore data shows that of the seven days in the last ten years where eCommerce has generated beter than $1 billion in revenue in a single day, six of those seven days have taken place this holiday shopping season.

And from the looks of it, iPads and iPhones are dominating mobile shopping. Apple mobile devices account for the bulk of all online non-desktop sales. Just over 92% of the sales originated from an iPad or an iOS-enabled device in December 2011, up from 88 percent in April, RichRelevance reports.

“The numbers across our retailing partners sites demonstrate just how powerful the iOS platform is enabling mobile web shopping and, while still below 5 percent in total conversion, mobile traffic’s doubling in eight months is a trend we only see accelerating,” said David Selinger, CEO of RichRelevance. “In order to succeed in this dynamic market, retailers and brands must ensure they are addressing relevance throughout the channels where people are shopping, ensuring a seamless experience across the interplay of device, context and consumer behavior.”

The findsings presented in the above study are based on more than 3.4 billion online shopping sessions, specifically those taking place between April 1, 2011 and December 18, 2011 on the web sites of US online retailers.
