OK - Here's another opinion:
Many people who say they don't like DSG (or automatics in general) seem to expect it to be telepathic. If you take the time to understand how it works - RTM! - it's not too tricky to get it working for you. For example, if you're accelerating smoothly in third, it'll have fourth ready for you. Therefore, if you want an extra dose of acceleration by downshifting, there will be a delay. Of course, you might feel frustrated by this, but remember i) it's still going to change quicker and smoother than you in a manual, and ii) it's your fault. Why is it your fault? Well, if you had been planning ahead, you would have had plenty of time to pull a paddle.
I regularly swap from autos to manuals, and I just don't have a problem anymore. I recommend bending your left leg (to take your foot away from where you subconsciously expect the clutch pedal to be) when in an auto, and always putting your foot on the clutch when starting a manual. Works for me, anyway.
Last word on the subject - you can't beat the sound of DSG's full throttle upchange!
