I have been trying to translate an article about wearable smart watches. The meaning of "shortage" in the text below is unclear to me: Does it mean lack of quantity or lack of quality or lack of facilities ?
There is no shortage of wearable gear out there, and really what I’m writing about here is the latest crop of smartwatches, most of which run on Android Wear. In the grand scheme, I know it is but a portion of what many of us may use, be it Jawbone’s UP, or Fitbit, or Samsung’s Tizen powered Galaxy Gear, and for me, it really comes down to a single issue. As I thought about that single issue though, I examined other factors that leave me feeling pensive about what lies ahead.
