I don't drink coffee, but my wife does, and he has been using the Keurig for over 2 years. She used to love and a use grind and brew setup, but it broke and she picked up a single serve Keurig, she loved the ease of the K cup, but she didn't like that she could only make 1 size. I believe it was 6 or 8 ounces, and she couldn't put anything bigger than a standard coffee mug under the fill spout, so she would make 2 coffees(with 2 K cups) and pour them into her disposable coffee cup to take to work. After about 6 months, she upgraded to a Keurig (B70)Platinum and absolutely loves it. Now she makes one 12 ounce(using 1 K cup) directly into her foam cup. She also utilizes Amazons subscription service, she has 50 Donut Shop Kcups delivered about every 4 weeks or so for $26. Hope that helps. If you plan on getting the B70, make sure you get the newest version, it is the one with the little flip top lid on the water reservoir.
my coffee maker just died, and my wife suggested i get a Keurig - primarily because her parents have a Senseo and they all seem to love it... personally, i think that coffee tastes like that s*** you get at 7-11, you know, hot bean water.
so instead i pulled out my old espresso machine and started making myself cappuccino every morning. not only is it marvelous, since i only have one cup o' cap, i cut down on my caffeine intake as well.
NOTHING beats fresh ground coffee made the way YOU like it.
