Microsoft has unveiled a new Surface laptop to compete with the Macbook Air.
The device will go on sale on 15 June with a starting price of $999 (£770). It has a 13.5 inch (34cm) screen and 14 hours of battery life, the firm said.
The tech giant also revealed a new edition of its Windows 10 operating system aimed at schools and designed to run on low-cost computers.
Experts said the move was intended to help Microsoft compete with Google in the schools market.
Microsoft Surface boss Panos Panay said the new laptop had a 1080 pixel display and weighed 2.76lb (1.25 kg) – lighter than the Macbook Air.
He also said it would run the new Windows 10S operating system and, despite the price, had been designed with students who were about to leave school in mind.
Carolina Milanesi, an analyst at Creative Strategies, said: “Apple’s Macbook Air is also popular with students and it hasn’t produced a new model for a while.
“So this is all about Microsoft trying to steal a march on its old rival.”
