ah yes - I had a similar experience. Little known is the quality of the Keurig. They stop working. My previous one had to be replaced after 5 years - and the replacement is 2 years old. However my old style Filter "Mr coffee" pot still works after 15 years.
The printer ink analogy comparison isn't quite right. You can't buy ink at the store. However you can buy coffee everywhere - it existed before K-cups. It is an industry by god! While the grocery store now stock mostly K-cups -- coffee is available from plenty of shops. Their failure was attempting to DRM something regularly available from other sources. Maybe like music - you can buy CDs..but Apple made it dirt easy to buy. Did Keurig make it easy to *buy* coffee? (brew/make it --- yes). Now it is harder to buy - and more expensive. And they didn't solve the Eco problem.
But the point is...my experience around K-cup 2.0 is like yours. When I go to the store to buy cups it has become confusing. At least they gave them a different name. People buy me coffee as a present - v1.0 cups thankfully because that's all they know.
Recently we switched to a refillable K-cup and buy bulk coffee. The TCO hasn't been very good for these machines. Expensive up front purchase, expensive coffee pods, and relatively short life. Couple that with the new machine forcing you to buy the even-more expensive pods - and I just didn't see a reason to switch.
Thankfully some innovators have made a reusable coffee pod device that fits in the native hole. The one Keurig provides is a PITA to operate.
v1.0 doesn't exactly make the best tasting coffee. I heard v2.0 was better...but the cost doesn't make sense.
