Yeah, that’s it in a nutshell. It’s pretty much like the difference between Starbuck’s and going to the local shop with the expensive La Marzocco. One is adequate coffee fast and the other is a sit down experience.
The Nespresso makes actual espresso, it’s not BAD (like the Kuerig for example). And while it doesn’t at all compare with a high quality press, the time it saves me is well worth it.
