what is the difference between keurig 1.0 and 2.0?
K-Cup 1.0 vs 2.0 The 1.0 and 2.0 cannot both use the same standard K-Cups, though they each have access to stronger brew technology. The biggest difference between the 1.0 and 2.0 is that the 1.0 can only use standard, original K-Cups, which are much smaller than the newer K-Cup for the Keurig 2.0.
