I was a non-coffee drinker, only really having expresso when out at a decent restaurant.
HOWEVER the Mrs loves her coffee and after sampling Nespresso, we're converted.
I even now drink coffee on a more regular basis.
The main reason I let the Mrs buy a machine is that it is a stylish addition (Cube) to the kitchen, it's easy to maintain and quick to make a coffee.

I'm a fan, however there's only the one outlet in London (Selfridges) as far as I know.
Although the Mrs works close, she prefers that we drive into town to buy it so we can stock pile!
You can do mail order, but that way you can't sample the special edition blends.
