Power Cover: Microsoft's keyboard cover for the Surface with a built-in battery
It was only yesterday that Neowin was able to pull back the covers on the Surface Pro 2 and highlight some of the features of Microsoft's upcoming tablet. While the specs are looking like a modest upgrade to the Surface Pro …
Context & Ripple Effects
Neowin's Power Cover scoop lands one day after the outlet's own look at the Surface Pro 2, in which it judged the specs a modest upgrade over the original Surface — a frame that makes a keyboard with a built-in battery read less like an accessory and more like a deliberate fix for the tablet's runtime ceiling.
The reveal traveled unusually far for an accessory leak: Engadget, ZDNet, TechHive, Pocket-lint, SuperSite for Windows, Windows Phone Central, Gotta Be Mobile and pocketnow all carried the same story on the same day, indicating Microsoft briefed the press broadly rather than letting the cover surface organically.
First-order effects
- Prospective Surface Pro 2 buyers gain a keyboard option whose selling point is extra runtime rather than typing feel, letting Microsoft market longer battery life without committing those cells to the tablet chassis itself.
- For Microsoft, the cover adds a premium attach-rate product to the Surface line at exactly the moment the Pro 2's headline silicon gains are being described as incremental.
Second-order effects
- Burying the battery in the cover shifts the cost of extended runtime onto the customers who want it, letting the base tablet stay thin while the full-battery configuration carries a higher total price — an upsell structure competitors who integrate everything must match on their own bill of materials.
Third-order effects
- If the pattern holds, Microsoft's hardware strategy splits the bill between device and accessories, with the keyboard layer absorbing capabilities — batteries today, plausibly ports or graphics tomorrow — that rival OEMs bake into the chassis, changing how Surface value is compared against integrated designs.
The trend: Microsoft is treating the Surface keyboard cover as a modular extension of the tablet's specification, moving capability out of the chassis and into the attach-rate accessory business.
