it's funny - this whole thing is just another chapter in my rant that 
just like in the natural world a heterogeneous environment is a sign of 
a healthy ecosystem.  sure, it may take more effort and complexity to 
support a heterogeneous environment - but it does increase your ability 
to survive changes outside of your control.

the fact that intel has something like %90 market share of CPU's was 
bound to have consequences, much like the fact that lord knows how many 
start-ups are solely dependent upon AWS :/
