I for one am quite happy with the top operation. A one touch system defeats the purpose of the press and hold which is safety. If there's a way someone could get their head stuck between the top and the top header of the windshield, it will happen with a one touch system.
And guaranteed, someone will put the top up while doing 60 kph and bend the framework and then call it an issue. I can wait out that long 20 seconds. Anyway, good luck in your gadget search.
