Reports IT market researchers Context, which claim Acer is currently leading the way as strongest player in the market for Ultrabooks have been met by a scratching of heads by rivals.

Last week Context said that Acer has 62 per cent of the market through Western European distribution in the last quarter followed by Toshiba, Asus and Lenovo. UK Asus spokesman John Swatton said that while the figures were about Western Europe as a whole, he would be surprised if the UK was different from the mainland.

He said that according to the retailers his outfit's  Zenbook was out-selling the other Ultrabook brands by quite a margin. He got in touch with Context who told him that the figures were based on what distributors were tell it. This could be explained by the fact that Acer is putting more Ultrabooks into distribution but they are not selling so well once they get to retail.  Most of the sales of Ultrabooks are coming through retailers, Swatton told us.
