What is the advantage of having an MX Blue switch on a mouse? Seems like, if anything, it would be less suitable for the purpose than a typical Omron mouse switch.
Doesn't seem to be anything special in other regards, either; the Avago 9500 sensor can be had in other mice that are cheaper and lighter, and I don't see any areas of particular distinction in the electronics.
So really, I don't see the point.
