Tablet computers are set to overtake netbooks in the near terms, although full-size laptops will still account for the most PC sales.
Research from Forrester indicates that consumers are starting to addopt a multiple-PC approach to fit their digital lifestyles.
The study reports that almost half-a-billion PCs will be sold to consumers in the US between now and 2015, but the share of the market among form factors will shift considerably.
Growth will come from new form factors like tablets, which will cannibalise netbook sales and account for one in four PCs sold to consumers, while full-size laptops will constitute the largest share of the PC market.
Desktops will be fewer in number but still an important segment, buoyed by growth in gaming and 3D.
