Well, I drove one today, an '05 with DSG - but no paddles.
I spent around 40 minutes with the car...driving on open roads and through busy traffic in the town centre. I tried D, S and manual modes. The gearbox has to be one of the best pieces of technology to come to the car. I put it into D as I left the garage and gently cruised up the road. To look down and find I was already in 6th was quite shocking - as I didn't feel ANY gearchanges...not in the slightest. The only way I knew I was in 6th was because the display told me so. In auto mode, this has to be the most exceptional auto to date.
In S mode, I don't know if the box had an issue or not, but cruising at 30mph it wanted to stay in 2nd ! We knocked it back into D - at which point it went up to 6th, knocked it back into S and it was staying in 3rd. Seemed a bit weird to me.
Manual mode ... using the stick for manual mode kept catching me out. I had no problem with when to change gear, this was fine. The issue was that I wanted to pull on the stick to shift up and push on the stick to shift down (in my head this just seems more sensible). So, I kept having to think about my changes - and a couple of times in traffic I got it the wrong way around.
Overall though, I have to say, I prefer the feel of manual. I know it was only 40 minutes behind the wheel, but even in manual -> using the stick, I still felt separated from the car, and it kind of reduced my opinion of the car overall. There was far less sense of occassion compared to when I drove the manual, and I did come away feeling quite disappointed in the car.
There is absolutely no doubt in my mind at all that DSG gearboxes will be everywhere soon, but at this stage they are not for me. I need manual - even if it does mean I take fractionally longer to get to 60 !

Also, today was the first time I realised just how much of the Skyline performance I will miss. There's no doubt that the GTI is a great performer and picks up speed well, but it truely is never going to be a match for my current car. I'm REALLY going to have to get used to that when I finally make the cross-over.
