While there's no reason to believe that the newest keyboard device from Kanex wouldn't work with any and all Bluetooth 3.0-compatible devices, they've aimed directly at the Apple world here in the week of this accessory's launch. The Kanex Multi-Sync Keyboard works with the iPhone, iPad, iMac, and any other machine (with Bluetooth 3.0 or higher) you think would match up nicely. You've got a full Apple-esque design to the board as well as Bluetooth switching buttons - that means you can press one button for device A, then switch to device B or C with a press of one of your total of three buttons.
This machine works with a "stylish yet comfortable" design that - again - is strikingly Apple-friendly aesthetically. The whole unit will ring in at $69, putting it in at just under comparable Apple-made wireless keyboards of this size. You'll be working with a full standard QWERTY keyboard lineup with a selection of Apple-friendly hotkeys as well.
Down in the lower left-hand corner you've got a button with an iPad/iPhone "Home" icon on it - this button does what you'd expect from the same physical button on these Apple mobile devices. There's also a dedicated Search button for iOS, and a set of buttons for OS X: Mission Control and Desktop View included.
The rest of the hardware here appears to be ready to roll with any other sort of Bluetooth 3.0 device - switching between your Android and Acer machines might be your choice of hardware, for example. That said, Kanex does include what they call an "iPhone/iPad Stand" in the box - surely wide enough and ready to roll for any other machines comparable in size and shape.
This device is able to pair with up to 3 devices working with Bluetooth 3.0, and is - if you have a peek down in the dirty details, compatible with one whole heck of a lot of devices besides the original three shown here: Apple TV, Windows and Android devices, iOS 4.0 or greater iPad, iPhone, or iPad mini, and the PlayStation 3. They also mention that the host device must be able to support Bluetooth HID profile - if you don't know, be sure to ask.
