The PC market is showing more stabilization, and now seems to have shaken off the gold rush fever of crypto-mining, overall volume slipped, albeit with bright spots for the market here and there.

JPR marks Q1'18 as the peak and last hurrah of the crypto-mining fever. Desktop GPUs, which went into mining rigs, have dropped back to their normal volume.

"We believe the market for AIBs for crypto-mining has ended and this will likely be our last mention of it," JPR commented.

Tablets too have seen a slowdown from their peak in 2014, and the forecast is that this once PC cannibal has saturated its market and will decline to a replacement status. It will also be in turn cannibalized by the smart new always connected detachable PC tablets.
