For me, it is my eye site, isn't as good as it use to be and everything 
has gotten way to small.
Just finished up building a controller and had to use a 5x magnifier.  
At least when you bread board stuff you can space things 2 microns 
further apart than half an atom:)
I think most hams are older now.  I don't see the younger crowd getting 
in to the hobby, sad to say.  So size of stuff is more important to me 
now.  As I wont tackle a project that requires a lot of smt components.
