Interesting. So French people are ok buying coffee for €90 a kilo to get this convenience? I can understand this only because traditionally, the French "Expresso" was guaranteed to be a watery, bitter, creama-less wish-wash.
Expressos you get in Cafés are usually good, if a little bitter (and not comparable to what you can get in Italy).
But coffee people made at home used to be, in my own experience and opinion, an abomination. Never hot enough, never strong enough.
The truth is, everyone wants something different (decaf, strong, stronger, lighter...)
The miracle of Nespresso is that you can serve different cups to different people, at the same time, which is impossible with most other means of producing coffee at home (or very difficult, complex and expensive).

That's really not my experience. I've found it consistently hard to find proper espresso in cafés in France; one usually needs to find the one place teeming with bearded hipsters (unfortunately), and you might be lucky to get an acceptable (not excellent) espresso.
Refill cartridges for an inkjet printer are, per liter of ink, also horribly expensive. Many other things are equally expensive when compared to the bulk price of the main ingredient. So what?

The way it gets evaluated is not "it costs €90/kilo for home-brewed coffee". It's "it costs €0.40 for a cup of coffee not too different from a proper espresso at a café".
