Hummm having owned stove tops, cafetieres, filter coffee, one of the 1st gen top of the line nesspresso machine and an aeropresso (for work natch, because it's either that or instant...*shudders*), I can say the areopresso at the moment is my favourite but the nesspresso does make a damn good espresso.
On top of that, they do also now accept the used pods back for recycling since they're aluminum so good for that sort of thing, or you can even buy reusable pods now for them (though that kind of defeats the purpose of having coffee so conveniently at the ready).
At any rate, they're pretty much always better than any highstreet coffee shops (with two local independents as exceptions, both grind and roast on-site can't beat it.).
I just wish everyone would finally stick to one standard for these things and be done with it rather than making a proprietary system everytime that gets junked when demand for the pods runs short making the devices useless.
