Keurig is great at one thing: making the worst coffee this world has to offer. That aside, I though they went to DRM enabled cups in the last few years in an attempt to block the aftermarket cup makers.
Having heard this from a number of coffee fans, I suspect you're not the market Keurig really targets. Rather I suspect we non-coffee-drinkers might be the primary buyers. We want something that will sit innocuously in the kitchen, looking good and doing nothing, on the off chance that we'll be expected to provide coffee for someone. We don't know how to buy coffee, we don't know how to prepare it, and we don't know how to clean up after preparing it. Also, we don't care to know any of those things. So, here's a something we made for you that came out of a fancy package. Now we're going to throw away this little plastic cup.
Now for espresso or the like, well that is a different story. We used to have an espresso machine but it was quite a pain (and took up space). For that the machines are great. We have the Nespresso machine with the milk attachment. Makes a pretty good cup. They provide mailing bags for you to send back the used cups? carts? (hum) for recycling.
Expresso machines are complex and bulky, and they generally aren't worth it unless you can spend $600+ (and that plus goes WAY up). Nespresso isn't bad at all (we have one here at work), but even better is a Lavazza machine, which takes cartridges like the Nespresso, but the resulting espresso is an order of magnitude better, in my opinion.
I'm a tea drinker myself, but have one around to serve decent espresso to people that want it.
The polite thing to do would be to accept the coffee or not, without placing conditions on the host, or implying that their hospitality is possibly beneath your standards.
After a couple of those, everybody knows your taste :D
If all you have is instant, you're better off not offering anything. That stuff is generally terrible.
I'd rather have a cup of Nespresso coffee than a fresh brewed cup of stale ground coffee.
Many larger food stores and most specialty coffee shops sell coffee beans by weight and will grind them for you. So you can easily by just a small amount at a time if you want.
Keurigs do a perfectly fine job by comparison.
I guess you've never had coffee out of a rarely serviced machine in the break room of a millwrighting shop.
Keurig coffee is the smoothest brew ever compared to some of the terrible coffee I've gladly drank over the years.
