Emerging markets are still showing interest in new tablets, but that isn't enough to sustain IDC's prior forecast for this year.
Shipments of notebooks hit 41.5 million in the second quarter, a gain of only 1 percent, but not too shabby after seven straight quarters of declines, says NPD.
Between April and June, a whopping 255.3 million Android-based smartphones were shipped worldwide.
The company says smartphones accounted for over half of its total mobile device shipments in the first half of the year.
South Korean electronics giant says it shipped 14.5 million smartphones in the quarter, a 20 percent year-over-year increase.
The number of personal computers worldwide is expected to drop 6 percent this year, according to a study published Tuesday.
Despite rapid gains in recent years, consumer appetite for tablets seems to be shrinking, thanks to demand for bigger smartphones.
The larger iPad is out-shipping the iPad Mini. That means the popularity early last year of the Mini has not been sustained vis-a-vis the 9.7-inch iPad.
Samsung, Lenovo, and other major players saw much higher growth in shipments, according to IDC's Worldwide Quarterly Mobile Phone Tracker.
Regardless, shipments of larger-screened tablets will rise over the next several years, says market researcher NPD DisplaySearch.
