Fewer and fewer people want to fondle a new slab these days with just 36.4 million units shipped worldwide during Q3.

This equated to 3.5 million fewer tablet devices sold versus the year-ago quarter, a drop of 8.7 per cent: traditional slates fell almost 8 per cent to 31.6 million and detachables were down 13.1 per cent to 4.8 million.
