With these devices poised to be top selling gifts, there's sure to be a subsequent explosion in the number of apps downloaded for the mobile hardware, experts say.
"What we see is the mobile app economy is very consistent with many consumer-facing economies, like retail," said Craig Palli, chief strategy officer of Fiksu, a mobile app marketing firm. "It has a profound spike during the holidays."

And that can mean big bucks for some app makers.
During the fourth calendar quarter, twice as many apps are downloaded than in a typical quarter, Palli said. And most of the action in the fourth quarter comes from downloads happening in December, he said.
This is certainly true for Apple, which sees a surge in the number of apps downloaded from its app store in December. Last year, a record of more than 2 billion apps were downloaded during the month.
What were all those new users downloading? Mostly entertainment and gaming apps, of course, according to data from the mobile research firm Localytics. And that pattern is likely to continue, Palli said.
"The amount of volume in the gaming activity is absolutely going to spike," he said.
