I have one I bought when I was working in another town, but now that I'm back home I haven't set it up yet. My Tassimo still works and the pods are cheaper. But Tassimo is on the decline so when the machine breaks or I can't find the pods I like I'll switch to Nespresso.
Both Tassimo and Nespresso are head and shoulders above Keurig because they're capable of actually pressure and don't taste like you dribbled hot water through a couple grains of coffee inside melting plastic...
Another benefit to Nespresso is the all-metal pods are very recyclable and the company helps with that directly. Compared to everybody "wishcycling" their other pods and probably just contaminating other recyclables.
Of course a grinder and espresso machine is even better, but the Nespresso comes close enough for me. I like to make a red-eye or two every morning (coffee plus a shot of espresso) and it's a bit expensive with Nespresso but tastes good. And even if you just like a simple cup of coffee, the Virtuo pod line has a lot of selections, very easy, and really does taste better than Keurig.
The only benefit Keurig has is price/availability.
