Surface Power Cover rumored to ship after the Surface 2, provide the whole family with extra juice

Despite Microsoft's claims that the Surface family of tablets was a representation of "no compromise," many road warriors have found the battery life to be... well, compromised. In order to address said concerns, it's looking as if Microsoft will be launching a line of Power Covers. In a nutshell, these battery-inclusive Type Covers will snap onto Surface tablets as the existing ones do now, but a bump in thickness (from 0.21-inches to 0.38-inches) will add "significant" life. Interestingly, WinSupersite is reporting that the covers won't ship until after the Surface 2 and Surface Pro 2, and the original Surface RT won't be compatible. Oh, and as for pricing? Mum's the word, as you might expect for an unconfirmed accessory.
