Tablet sales are already being made at the expense of laptop and desktops and the rate of cannibalisation is expected to grow.
Research from YouGov has shown that 8% of those that have recently bought a tablet have done so to use it as a replacement for a desktop or laptop.
The vast majority of those picking up iPads and Galaxy Tabs along the high street are planning to use it as an additional device but YouGov expects the number of replacement purchases to rise.
"YouGov believes the proportion of consumers choosing to purchase tablets substituting for laptops, desktop computers and netbooks is expected. The launch of newer, cheaper tablets throughout 2011 will further boost this increase," the research firm stated.
Price is still seen as a major influence on the extent of the spread of tablets and YouGov believes that once it hits £250 demand will really take-off.
