I'm sure we each overestimate our importance. Plenty of my non tech friends went out and bought tech without asking me, heck they probably know i'd tell them not to buy that windows phone on a plan but they did anyway because it came with free spotify.

I think the better insight is that our needs, for practicality and occasional updates, are quite common. Its nice to add more memory or disk without needing a new machine. It would be nice to have a replaceable battery in my laptop. Apple is screwing up all these simple things.
