This is something I thought was cool from last week Blades = generic name for their keyboard covers. So far they've all been QWERTY keyboards but they showed off a cover with a DAW control surface, faders, and drumpads We know even though they didn't release any peripherals that used it, the original Surface was outfitted with extra pins to transfer current between it and the peripheral. This is how that upcoming power cover is able to charge the unit and how the new keyboards are backlit. The cover also allows for data flow, so once the blade is connected, it can autoinstall companion software - that's how the Remix blade works. Microsoft regularly gets pegged as being lousy at hardware because of their Zune flop and the fact they've historically monetized through software but one hardware market they've entered/succeeded that's never talked about is peripherals. It wouldn't be a stretch for them to leverage their expertise on peripherals to create more innovative blades. Being good at peripherals is how they managed to fit a mechanical keyboard inside a ridiculously thin cover while Apple is still charging people $50 for a piece of polyurethane whose defining feature is it folds into a triangle. What would be really interesting is if they released an SDK and allowed for third parties to create blades. This could blow up as a submarket catering to everything from niche applications to cinnib workflow related. Things like solar panel blades to covers for video editing, user customizable blades, game specific blades, etc And before someone says a Blade is a ripoff of Logitech iPad keyboard case, no, this is the first time you have a peripheral that's able to transfer both data and power in both directions and with practically zero burden on the user (no pairing process, usb dongle, etc). I have no clue how MS's execution on the concept will be (execution isn't one of their strong points) but I think there's a ton of potential here.
