I understand your sentimant, and agree that there are a lot of poorly/uncreatively placed micros.
However, I've seen some brilliantly placed micros in wonderful locations where there's no way you could put a regular-sized cache. Also, I've seen some full-size caches in some not-so-great locations.
So, I guess I disagree with both you and the OP. I don't think it's about the size of the cache, but, rather, the quality of the cache.
