A growing percentage of tablet owners have completely replaced their PCs with the mobile device, according to research released by YouGov's Tablet Track survey.
The survey of 4,271 individuals finds 8% purchased a tablet device instead of, or to replace, a PC.
Russell Feldman, associate director for technology and telecoms consulting at YouGov, said, "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."
"Of those looking to purchase tablets in future, 16% want one as a substitute to a laptop and 9% as a substitute to a netbook," he added
In a statement released today, Acer expects PC shipments to decline "approximately 10% from the previous quarter" in the second quarter of 2011.
The company blames its "recent company reorganisation, inventory adjustment and the seasonal slow-down of the PC industry in Q2".
Dell shipments fell 2% for the first time in six consecutive quarters at the beginning of 2011. Bryan Jones, public and large enterprise marketing director for EMEA at Dell, recently said consumerisation of IT was one of the biggest challenges impacting businesses purchasing decisions.
Despite rising tablet sales, Dell will continue to offer a full "balanced portfolio" of products and invest heavily in its tablet line.
"Dell wants to see more time and distance [over the next few quarters] before making any decisions," he said.
