I'm just wondering, as I'm contemplating getting hold of a Razer smart band to complement my Microsoft Band (for the social aspect really, the Band handles the heavy duty fitness tracking and heart rate monitoring) what the differences are between the Nabu/Nabu X, and how well are they supported on Windows Phone?
I'm not sure on the Windows Phone compatibility part, Razer's web site lists only iPhone and Android compatibility.
As for the difference tho, the original Razer Nabu has a small screen at the top of the device. I'm not sure if Razer had abandoned this device or not tho, as there doesn't seem to be much news about it any more and a very limited supply of devices (that usually go for a premium on eBay).
The Nabu X does *NOT* have this screen on top, but instead has three LEDs (RGB) in it's place...
At this point tho, unless there is a creative work around I don't know of, I don't see "official" Razer support for Windows Phone just yet.
