Sales for PC devices keep getting worse. Figures released by Gartner recently show that PC sales in Western Europe dropped by 12.8% during the third quarter of 2013, declining faster than expected.

The analyst firm pinned the decline on consumers increasingly buying new tablets instead of updating older ones.

Several announcements for AiO PCs made at the Consumer Electronics Show 2014 could change this.
