PC shipments worldwide reached 123.9 million units in the second quarter of 2014, representing an on-year growth of 14%. But with effectively no sequential growth, it would appear that the positive effect that tablets have had on overall PC shipments is beginning to wear off. Apple continued to lead the market with a 14% market share, though a 10% increase in Mac shipments could not make up for a decline in iPad sales, resulting in the company's overall shipments declining by 5%. Lenovo had another impressive quarter, with shipments up almost 20% on year, boosting its share to just below 14% - some 780,000 units behind Apple. Rounding off the top four, both Hewlett-Packard (HP) and Dell posted on-year increases in shipments, at 11% and 14% respectively, leading to sequential increases in market share, according to Canalys.

Worldwide tablet shipments fell approximately 5% sequentially to 48.4 million units, as Apple and Samsung suffered shipment declines. Apple shipped just under 13.3 million iPads in its weakest quarter since the first quarter of 2012. Samsung shipped just under 8.9 million tablets during the quarter, which represents a sequential decline, albeit not quite as sharp as Apple's. Apple and Samsung continue to account for 46% of global tablet shipments, and as a result many markets hinge on their combined success. Tablet shipments in Asia Pacific (including China) came in 8% below first-quarter-of-2014 numbers, mainly due to a fall in shipments by the leading pair. Conversely, both companies fared better in the US, and as a result, tablet shipments there increased 4% on quarter. Shipments in EMEA fell approximately 11% on year, with declines in Central and Eastern Europe, and Western Europe negating growth in the Middle East and Africa. Vendors and channel partners alike will have to closely monitor global inventory levels, which are already having a negative effect on Western Europe, where sequential shipments fell some 18%.

"A slowdown in the pace of innovation is creating an issue for tablet vendors. The tablet market has quickly found itself in the same position the notebook market was in some years ago, with minimal increases in hardware performance forming the basis for an argument to upgrade," said Canalys senior analyst Tim Coulling. "But when considering the most common tasks that tablets are asked to perform, the need for more horsepower is often not evident. Vendors will need to work harder to give reasons to upgrade if things are to improve in the third quarter. In addition, as smartphone screen sizes increase, the potential for such products to disrupt the market for 7-inch tablets is also increasing."

"Pricing remains Apple's biggest barrier to growth and essentially locks it out of a number of markets," said Canalys research analyst Rushabh Doshi. "By holding firm on its prices, Apple ensures that its tablet business is highly profitable. But as sales in its key markets slow, it is betting on the improving economic environment in high-growth markets, such as China, to drive future growth." Samsung faces a different challenge: it is fighting battles on all fronts as it attempts to compete in a wide range of market segments. "The release of the Galaxy Tab S line saw it add Super AMOLED screens to its tablet offerings as well as introduce a new 10.5-inch screen to its portfolio. With Samsung playing in so many segments, it is able to find pockets of demand. But it also drives obsolescence in other areas of its portfolio, causing inventory buildup that necessitates rounds of promotional activity," said Doshi.

The notebook market enjoyed a resurgence in the second quarter 2014, with shipments all but flat on the same quarter a year ago. With 49.1 million units shipped in the quarter, notebook shipments surpassed those of tablets for the first time since the third quarter of 2013. Shipments in North America and EMEA were up 13% and 8% on year, helped by good growth in Western Europe and the US. The growth in developed markets can be attributed to a number of factors. Improving economic conditions and ongoing XP migration continue to drive a refresh in the corporate space. Chromebooks are gaining traction, with increasing demand from consumers and education, especially in the US. Intel's Atom-based Bay Trail platform and the falling price of touchscreens are driving down the cost of consumer notebooks.

"It is a little premature to expect a large-scale refresh, but pricing has now reached a point that is starting to stimulate demand," said Coulling. "Consumers can expect further price cuts in the second half of 2014 as Microsoft responds to the increasing threat from Google. It has dropped licensing costs on small form-factor tablets and announced Windows with Bing, which will provide Windows for free on low-cost notebooks. Falling prices are great for consumers but will do nothing to ease the pain for vendors, whose margins are under constant pressure."
