Report: Haswell and Windows 8.1 will have only "muted benefit" for PC market in 2013

The PC market is expected to decline by 10 per cent this year, according to Citi Research, which revised its forecast downwards on the basis of weaker than expected demand.

The financial firm previously estimated that there would be negative growth of 4 per cent in 2013 when compared to last year, but that decline has now more than doubled in Citi's latest report to investors.

Slowing laptop production is seen as a contributing factor, according to CNet. Citi also dismissed optimism over Intel's latest Haswell processors and Windows 8.1, codenamed Blue, stating that they have had a “muted benefit” on the PC market.

The news might even be worse for PCs long-term, as Citi previously expected a modest rate of growth at 2 per cent between 2014 and 2015. Now, however, it expects that growth to be cannibalised by tablet computers.

Citi predicts that desktop computer shipments will fall from 148 million last year to 137 million this year, while laptop shipments will see a similar decline from 201 million to 179 million.

Tablets, on the other hand, will continue to boom, with shipments expected to reach a whopping 237 million, a staggering increase over the 144 million in 2012. Demand for tablets in emerging markets is seen as a major factor in this growth.
