I still say that if you have used all of your preset space most of the things you have stored are either substandard versions of other patches or stuff you never use.
"Substandard"? How do you know what is standard, good, great, or useful for another person? If a person collects stamps or guitars or guns, there may be ones they never "use" but still want and even cherish. (I am not a collector but I understand the sentiment.) Some patches I rarely use, but I still scroll through all the presets occasionally, sometimes at random for inspiration or fun, for example Simeon's patches. I also like being surprised, like "oh, that sounds awesome, I forgot about that."
Yes, we are spoiled to a degree. Do we NEED a MKII? Did we NEED the MKI or any other iteration after the original? Do we need an Axe as opposed to a POD ... ?
The answer to if your house is too full of stuff to move is almost never buy a bigger house, particularly as the house in this case was already huge.
Yet that's exactly what some people do, like it or not. I might not do that myself, in fact about 5 years ago I sold almost everything and don't even have a home right now,
but I am considering the MKII.
A better analogy might be: "We have 4 kids with twins on the way, we want/need a bigger car!"
Or: "I love my man-cave studio but I can't walk around w/o knocking over a guitar. I want/need a bigger room!"
Yes, these are first-world concerns. We are lucky to be in this position to even consider upgrading.
