We also use the Francis!Francis! X1 at home, although ours is stainless for the full Buck Rogers effect. Nice machine. It intimidates my children...which I consider an ancillary benefit.
At the office, though, we use an
Alessi Coban machine that uses the Nespresso capsules.
Clean, quick, efficient and tasty. Perfect for that environment, IMO, when you don't have the time or desire to be measuring and grinding beans.
