Last week, we saw BlackBerry show off its “PlayBook” tablet computer to face off against the Apple iPad and horde of Android slates. So what is the big M doing?

We’re hearing rumours suggesting that an announcement will be taking place next week on October 12. The expectation right now is that it will be a very Windows Phone 7 friendly spectacle, with the first phones being shown off from HTC and Samsung running the new operating system.
But the word today is that it might not just be phones.
New rumours today suggest Microsoft could show off a slate device designed to take on the iPad and give it some real competition by Christmas. Whether it runs a similar incarnation of Windows 7 as found on computers today or a version reflecting that of the new phones remains to be seen.
We’ll let you know next Tuesday.
