According to Business Insider wearable devices are to see "plenty of growth" in the long run-- global shipments should reach 148 million by 2019, growing at a CAGR of 35% from 2015 shipments of 33m units.

Currently short term wearable growth faces a number of hurdles. The main ones are the need to connect to another mobile device for most functionality and customers not knowing the benefits of wearable devices, although one can also points out (still) too high pricing, lack of functionality, arguably unattractive styles, limited battery lives, small displays and a lack of an adoption-driving killer app.

Global tablet shipments fall by -7% Y-o-Y (or -3.9% Q-o-Q) to reach 447 million units during Q2 2015 IDC reports, a quarter marked by little in terms of either hardware innovation or vendor portfolio updates.

"Beyond the decline, we're seeing a profound shift in the vendor landscape as the top two vendors, Apple and Samsung, lose share in the overall market," the analyst remarks. "In Q1 2015, Apple and Samsung accounted for 45% of the market and this quarter, with the growth of vendors like LG, Huawei, and E FUN, their combined share dropped to 41%. Each of the growing vendors managed to address available pockets of growth in the market; connected tablets for LG and Huawei, larger tablets and 2-in-1s in the right price bands for E FUN."

According to Strategy Analytics smartwatch shipments hit a record on Q2 2015, reaching 5 million units with impressive 457% Y-o-Y growth-- and the Apple Watch makes it to top status as it captures 75% market share.

Shipments for the quarter are higher than those of overall 2014 reaching 1.6m units.

"Apple Watch launched in 16 major countries and saw decent take-up from iPhone loyalists in the US and elsewhere," the analyst says. "Apple Watch has clearly raised the bar for the global smartwatch industry. The ball is now in the court of rivals, like Samsung, to respond.”

Global smartphone shipments total 337.2 million units in Q2 2015, an 11.6% Y-o-Y increase driven by robust growth in many emerging markets as Apple manages to snag some market share from current leader Samsung.

On the other hand overall mobile phone shipments (feature phones + smartphones) drop by -0.4% Y-o-Y to 464.6m units.

"The overall growth of the smartphone market was not only driven by the success of premium flagship devices from Samsung, Apple, and others, but more importantly by the abundance of affordable handsets that continue to drive shipments in many key markets," the analyst says. "As feature phone shipments continue to decrease, vendors will continue to attack both emerging and developed markets with competitive smartphones that are both rich in features and low in price."
