A couple of days ago I finally got the new Microsoft Surface Keyboard to replace my Microsoft Designer Keyboard which I used for the past year. If you just have a quick look at it you might see not a lot of differences, but the new Microsoft Surface Keyboard is a great successor of the Microsoft Designer Bluetooth Keyboard. It is also a Bluetooth keyboard using 4.0 and 4.1 LE, it has a slightly changed key layout and of course it comes in a soft-finish grey as the Surface Pro, Surface Book or Surface Studio, making them a perfect match, and the finishing touch to a well thought-out desk space. Besides these small design changes Microsoft worked on the keys. The key travel and spacing are perfectly engineered for fast, quiet, and responsive typing, making it feel much more premium.
For me, this is the perfect keyboard right now, since I prefer the flat key design which matches the ones of the Surface Pro and the Surface Book.
