Samsung's Galaxy Tab jumped 5.8 percentage points year-over-year while Kindle Fire lost 11.4 share points, according to the latest MobileSTAT reports from Jumptap, the mobile advertising platform of more than 218 million U.S. consumers.
Google's year-old Nexus tablet is now on the radar with 2.3%, while the Barnes & Noble Nook registers a mere blip at 1.2%.
Putting it all in context however, the Apple iPad continues to rule with a 70% share of total mobile traffic, based on Jumptap's research.
The iPhone continues to grow as top smart device, increasing share by 9.6 percentage points year-over-year. The iPod Touch, however, has lost a significant 10.1 percentage points of share -- signaling that consumers are seeing less value in a smart device that cannot make phone calls, according to Jumptap.
On Friday, Samsung introduces in the U.S. market its Galaxy Mega, a hybrid phone/tablet with a jumbo screen.
Apple is expected to ship two new iPhones in September.
Amazon, meanwhile, is selling from its home page “certified refurbished” 8.9-inch Kindle Fire tablets marked down from $239 to $179. It's a Deal of the Day.
Meanwhile, despite predictions of their demise, apps continue to be strong. According to ad requests on the Jumptap platform, 84% of mobile traffic now comes from apps rather than mobile Web sites. Two years ago, the split was roughly 50/50.
