Samsung, which surpassed Nokia as the world’s largest maker of mobile phones in 2011 and overtook Apple in smartphones this year, showed off a Windows 8 phone late last month. It didn’t announce an availability date either.

_ SURFACE

Microsoft plans its own tablet computer, too. It’s new territory for Microsoft, which typically leaves it to others to make devices using its software. Now, it will be competing against its partners.

The Surface tablet will come in two versions, both with 10.6-inch screens, slightly larger than the iPad’s. One model will run on phone-style chips, just like the iPad, and will be sold for a similar price. A heavier, more expensive version will run on Intel chips and be capable of running standard Windows applications. The Surface will go on sale on Oct. 26.

_ NEW BLACKBERRYS

A year ago Research In Motion Ltd. disclosed that it was working on a next-generation phone system for the BlackBerry, which now looks ancient next to the iPhone and Android devices. It was supposed to be out in time for this year’s holiday season. That won’t happen.

In June RIM pushed the release of BlackBerry 10 devices into early next year, saying it wasn’t ready. That means RIM will not only compete with the new iPhone and Android devices out this fall, but it will also have to contend with the new Windows devices.
