In the two months since the iPad launched in the UK, YouGov has found that 96% of the 713 iPad owners surveyed owned products such as an iPod, iPhone or Mac.

Russell Feldman, YouGov’s technology and telecoms research manager, said: ‘By Christmas this is expected to be a much more crowded marketplace, with a number of consumer goods brands providing alternatives to the iPad.’

A total of 713 UK iPad owners were interviewed in the online study between 27 July and 2 August.

BlackBerry manufacturer Research in Motion and Samsung are both expected to launch a rival to the iPad before Christmas. Acer and T-Mobile are also tipped to enter the tablet market in the next few months.

In Apple’s recent 2010 Q3 results, ending 26 June, it attributed a 77% increase in profit to sales of its Mac, iPhone and iPad. The company sold 3.47 million Macs, 8.4 million iPhones, 9.41 million iPods and 3.27 million iPads during the quarter.
