Microsoft Corp is developing a small tablet-style PC to rival a similar product that may be launched by Apple Inc, technology blog Gizmodo reported on Tuesday.

The booklet-shaped device, called Courier, is in the late prototype stage of development, Gizmodo reported, without identifying the source of its information.

Microsoft did not immediately answer a request for comment.

The Courier device has dual 7-inch screens that are touch sensitive and can be used in conjunction with a stylus, Gizmodo reported.

Apple has long been expected to launch its own tablet PC -- essentially a large version of its iPhone -- but has so far announced no plans to do so.
