Not so much stopped using Z80s, but it was a timeline thing, I believe. 
  Torch grabbed market share early on because for the same price as 
Acorn's (and others) dual drives, you got a Z80 thrown in, or looking at 
it the other way round, it cost less (?100 less) than Acorn's Z80.  It 
also got to market months (maybe a year?) before Acorn's Z80.  However, 
Torch had all but gone under by the time the Master appeared.

The downside was that Torch CPN was not CP/M, by any stretch of the 
imagination, and much of the common CP/M software wouldn't run on it 
because the memory map was incompatible.  In the long run, Torch lost 
out because of it.
