Regarding the "weight problem",my Milano isn't significantly heavier than a standard hybrid;it just feels funny when you pick it up because the weight is concentrated in the rear wheel.
I don't mind the roller brake at all. I can drag it coming down a hill without trashing a set of brake pads. And rear brakes aren't for stopping. They're for scrubbing speed,holding the bike on a hill,and keeping the back end in place when braking hard. The front brake is what does most of the actual stopping. If I may rant for moment,why the frag do all these 'commuter bikes' that come with Nexus or other internal hubs come with rim front brakes? I wouldn't think of regularly riding in bad weather without discs.
As for the grip shift;yeah,they should've just updated the thumb shifter from the older 7 speeds. Much nicer.
