For quite a long time now, I've been fighting back against the term "fragmentation". I have never argued that problems don't exist, just that the term "fragmentation" has such a broad meaning as to be essentially meaningless. These days, rather than just give up on using the flawed term in favor of more accurate descriptors, it has become more popular to turn the word "fragmentation" back on its original creator, Apple, but this just further muddies the water...
