parfais for PC ...

Strong point:

the height and depth adjustments
very comfortable keys
the backlight (although the color change seems useless but hey it's true that his class :-))
the top shortcuts headbands and sides
WASD keys, space and reinforced arrows
usb port and headphone and microphone integrated socket
gold-plated connector emulators
are packaging
design

weakness:
the price
not compatible with mac (there are but the latency is at the rendezvous if bootcamp)
go for the picky it is regrettable that the cord is a bit short and its width (the lateral access to the shortcut key requires some flexibility)
Brief cyborg does not disappoint us (again) with this keyboard and yet I had the last apple keyboard is very versatile and complete it would have earned 4 see 5 star if only it was compatible mac .....
