Where Windows Phone worldwide sales is dropped to 0.7% market share only, next point of discussion is Microsoft Band. Microsoft probably won't release a Band 3 this year (or later). Didn't find statistics on market share on this, but would be pity if both Windows Phone and Band are end of life. Where other wearables must be used with the same operating system, Microsoft Band can be used in combination with your favorite phone. There are health apps for both Android, iOS and Windows Phone available.
Besides of that current Band is cheaper now, where price is dropped with $75 (temporarily). When looking for wearables market share, Microsoft is not mentioned at all. Maybe sales on Band is as worse as Windows Phone, where Microsoft stepped in to late to make a difference! Time will tell, because Microsoft has planned a device event on October 26th already. Hope that announcements are coming on both expired and future devices.
My personal experience on Windows Phone:
Microsoft Lumia 950 experience after 9 months (pro's and cons)
Microsoft will be ending sales of all Lumia smartphones by end of this year!
Other news on Microsoft Band 3:
Microsoft probably won't release a Band 3 this year
Don't expect a new Microsoft Band device this year (or maybe ever)
And finally: Microsoft Band to be dumped and more
