Apple has held on to first place in the US education market, and become the second-biggest unit-shifting PC company in Japan.

A US education market report from International Data Corporation shows that, in the fourth quarter, sales of DV-equipped iMacs helped drive Apple's market share up to 30.6 per cent.

The report also revealed that, overall in 1999, Apple enjoyed a 23.6 per cent share of sales in the US education sector.

Meanwhile, Japan-based magazine Computer News reports that Apple’s market share in Japan was 20.1 per cent in the week ending February 27, behind just NEC, with 21.9 per cent. Apple’s recently-announced iBook SE was the country's top-selling laptop.
