Sure. And the Galaxy S3 was not available with 128 GB NAND. Neither is the S4. Neither is the iPhone 5s. In fact, I'm not aware of a single flagship phone with that option. And if/when one finally appears, it will no doubt be priced $200+ over its 32 GB counterpart. The microSD cost me $40.so, just pointing out the obvious here but, if you had 128 GB internal storage (non swappable), you'd be better off than you are now with swappable storage.
I'm not quite understanding your point. Is the implication that if "all" (5%) of us nerds who keep demanding microSD would only shut up, manufacturers would start giving us more internal storage to compensate? Highly doubt it.
