Are hub gears & roller brakes as awesome as I imagine?

This is a good example of a bike with all the utility checkboxes ticked:

I saw these at the bike show and was really impressed with the quality and cleanness of it. Sure it's not your track bike or ultralight racing bike... but for every other need I'd rather have one of these.

that remind me of the new Trek Soho which look pretty good, not got all the feature like the Metropolitan thought (rack, light, etc.).
