What capsule machine were you looking at? I can wholeheartedly advise against Nespresso, especially if (1) you’re the type to buy with purpose, or (2) you like good tasting espresso.

1. Nespresso is owned by Nestlé. Should be enough said, but if you don’t know why they’re one of the worst corporations in the world, look it up. They’re basically comic book supervillain evil. Fortunately other companies do make pods that are able to fit and aren’t licensed (from what I can tell) so it’s possible to use without supporting Nestlé (other than the initial purchase of the machine, but even then there’s probably unlicensed Nespresso-compatible machines too).
2. Unless you’re exclusively doing milk drinks, Nespresso pods just aren’t that good. They taste weak and thin, and are wildly expensive per gram compared to every other option available. If all you drink are lattes you probably won’t care as much but if you like straight espresso, those pods are shit honestly. I’m not even much of a coffee snob and I find them really unpleasant to drink.

I don’t have as much experience with other pod machines, but I’ve had a couple drinks from a Keurig and it was just kind of mediocre at best. I totally get the convenience thing though, I’ve got a baby who’s started daycare now and making coffee in the mornings can be rough while trying to deal with everything else. But if it were me, I’d steer clear of pod machines, especially Nespresso.
