I love the DSG. It's cool, it's modern, it's the future. I'd have no trouble going back to manual, but I wouldn't do it on purpose.
I did have a bit of a "moment" coming out of work this evening! I thought I was driving a manual, and tried to change down approaching a junction, stamping on the brake rather than the non-existent clutch, and pushing the DSG into manual. Fortunately there was nobody behind me and I managed to re-group in reasonably short order.
