The proper bean to cup machines do produce a nice cup of coffee and we love our De Longhi - it's got a push on milk tank/ frother so cappuccino at the press of a button.
Bean to Cup machines do have their downsides tho, they require de-scaling and a filter change quite often - we live in a very "soft" water area and the warning light comes on all too often. A hard water area must be a nightmare because the warning light comes on at the wrong time every time and it does not let you cheat !
They only produce one cup at a time.
An Espresso is plenty hot enough but I never think a cappuccino is quite hot enough, even if the cups have been on the warming plate!
Having said that, I would definitely have another machine.
