Microsoft don't have to 'allow' Android apps to run under Windows. It's an open platform, anybody can write an emulator or create a VM environment with no involvement from Microsoft.
I assume the article is implying that Microsoft is itself developing this ability, either as a standalone application or directly within the OS?
Intel CEO stated just the other day that production starts in this quarter and shipping H2CY14. There may be some Broadwell models that won't ship until next year but I'm sure the Mini would only use the standard mass-market models which should be delivered this year.
Maybe not when it is first released, but currently it is expensive for its out-of-date specification. At this point Apple might as well wait for Broadwell to become available from Intel unless they plan to speed up the refresh cycle on the Mini. Otherwise in a couple of months it will be architecturally out-of-date again.
So the display is very expensive, the batteries are expensive and the external case is expensive compared to the iPhone yet Apple are able to sell the iPad, and make good margin, cheaper than the iPhone - and people claim the iPhone isn't overpriced.
iOS 7 runs like a dog on my daughter's iPhone 4. She would love to go back to iOS 6 and have a device that isn't frustrating to use. There certainly is no excuse for stopping downgrades for wifi only devices such as the iPod touch or wifi only iPads. It becomes a little more problematic with cellular device due to baseband firmware but nothing insurmountable.
