Excerpt: The Microsoft Arc's name comes from its curved chassis, which bulges upwards in the middle and slopes gently forward. This design makes the Arc pleasant and comfortable to use, as well as giving it an elegant, eye-catching look.
Conclusion: I've been a fan of Microsoft's hardware products for a long time. That being said, this keyboard is no exception. It is well made, easy to type on and very attractive. It's not designed for every computing environment. But with the micro-receiver that attaches magnetically to the bottom of the keyboard, and the sleeve for transporting the keyboard with other mobile devices, it makes for a very nice mobile accessory.
