Windows 8 is an awkward one for us. It's basically a PC operating system, which we don't cover, but Microsoft stubbornly insists PCs include tablets, which we do cover. Still, who says things should be neatly compartmentalised after all?
Er, anyway, the point is that Microsoft has announced that its tablet OS Windows 8, which also runs on PCs, will officially launch on October 25.
That's in just over a month's time, but the news isn't much of a surprise given how Microsoft made it known back in July that Windows 8 will officially go on sale on October 26.
But with Windows Phone 8 also getting its last few coats of paint ahead of its general release, it's good to have the dates confirmed.
What the Save the Date invite doesn't confirm, however, is whether (as was claimed in July) the Microsoft Surface tablet would be fully unveiled at the Windows 8 launch event.
Maybe it's reading too much into his comments, but the way Steve Ballmer was talking about the Surface in an interview published over the weekend, we're not 100% confident it'll be ready to go on time. We'll hopefully know more soon.
