Not a big fan of Nespresso, but it is convenient for offices or hotel rooms. Although for this I really prefer the LaVazza espresso point system machines, which are much better.

At home I use Illy's E.S.E. pods and find them just as convenient but much better tasting. I also like how I am not committed to using any particular brand of coffee. I can use standard grounds with my machine, or can buy E.S.E. pods from LaVazza or other companies if I choose.
