According to a report by Accenture (NYSE: ACN), smartphones, tablet computers and 3DTV sales will go up in 2011.

The research giant predicts consumer purchase rates of PCs and mobile phones (excluding smartphones) will decline by 39 and 56 percent respectively this year.

On the flip side, Accenture expects buying rates of 3DTVs to jump by 500 percent (a rate not that surprising for a virtually new market); tablet computers - 160 percent; ebook readers - 133 percent; and smartphones - 26 percent. The company's annual survey found that only 17 percent of survey respondents plan to buy a desktop or laptop computer in 2011 -- a 39 percent drop from 2010.

Accenture said its annual survey focuses on usage and spending on 19 different consumer electronics technologies among more than 8,000 consumers in eight countries in both emerging markets and developed economies: Brazil, China, India, Russia, France, Germany, Japan and the United States.
