NEW YORK -- Microsoft is expected to announce new Surface tablet computers, including a version with a smaller screen to compete with Google's Nexus 7 and Apple's iPad Mini.
The company has an announcement event scheduled in New York Monday.
It comes about a month before Microsoft releases an update to its Windows 8 operating system on Oct. 17. Among other things, Windows 8.1 will be usable on smaller touch screens, which have become popular because they are cheaper and easier to carry.
The new Surface tablets could also get lighter and thinner thanks to a processing chip that uses less energy and doesn't require a fan.
Microsoft began selling Surface tablets last October, but sales have been slow.
