The company says that year-on-year growth will stall at about 6.5%, significantly less than the 12.1% that it originally put forward. What's spectacular though is how fast tablet growth appears to have stuttered.
Actual y-o-y growth in 2013 in so-called mature markets (North American and Western Europe) reached 25% while that number was much higher (88%) in RoW territories.
Now, IDC reckons that it will be flat (i.e. 0%) and 12% respectively with 2018 forecasts set at 4% and 5% respectively; about 233 million units will be shipped, a number that includes both tablets and 2-in-1 convertible/hybrids.
IDC's research director for tablets, Jean Philippe Bouchard, argues that shipments are likely to growth thanks to newer tablets with small size displays (less than 8-inch), many of which are expected to run on a free copy of Microsoft's Windows, 8.1 with Bing.
When it comes to revenues though, average selling price for mature markets is still holding well at about $373 (about £220, AU$ 400) far more than in the RoW where ASPs slumped by 10% to $302 (about £190, AU$330); that's thanks partly to a shift to large screen (>9.7-inch) and embedded cellular connectivity (3G/4G).
In some Asian countries for instance, growth of voice-enabled tablet topped 60% and represent a quarter of overall tablet shipments, with many seemingly preferring the tablet as their unique device rather than the smartphone.
