The total portable PC market is expected to grow 26% to 215-million units and $117-billion in 2010, according to a new report by DisplaySearch.

In its Quarterly Advanced Notebook PC Shipment and Forecast Report, the company says dramatic increases in the size of the slate-style, or tablet, PC market are expected to be driven by the Apple iPad and that tablets from other PC brands that are expected to be launched this year.
It expects tablets to take some market share from clamshell-style netbook PCs, as well as lure customers that desire more functionality away from the e-reader market. The company also foresees the majority of tablet volume to ship into the North American and Western European markets due, in large part, to Apple’s distribution plans and known content agreements.
The mini-note/netbook/slate category will be the fastest-growing segment of the portable PC market for 2010, it says, propelled in part by the introduction of tablets. However, clamshell style devices will continue to grow as well. In addition, it expects continued strong growth in emerging markets and a recovery of B2B spending in the second half of the year to lead to 25.7% Y/Y growth as the market surges towards 215-million units.
