Tablets take off in 2010
Tens of millions" of tablet computers will be sold in 2010, according to technology analysts at Deloitte.
The keyboard and mouse-free devices are likely to be a top trend among consumers, they anticipate.
Deloitte's prediction fuels rumours that Apple is set to unveil a tablet-style computer at a press event it is hosting on 27 January.
However, the impact of tablet sales on the
burgeoning e-reader market could be substantial, the report said.
"
For every million net tablets sold there will be a corresponding impact on e-readers," said Jolyon Barker from Deloitte's Technology, Media and Telecommunications department.
