PON and AE both have their strengths and weakness and make sense for 
different deployment scenarios. My biggest problem with PON is that it 
seems some operators build their fiber plant for PON for all deployment 
cases and then it's extremely hard to back out of it and switch to AE. If 
you have AE you can switch to PON fairly easily, but not the other way 
around if you've put splitters in the manholes.
