I'm not terribly excited about the dual clutch setupm but it's way better than a regular automatic, and should be able to bump start with a bit of logic though (it should be fine to bumpstart it given it IS a glorified manual) so I wouldn't be too put out if my next car had one.
I think overall it is a good thing. You would have redundant clutches if something happens to one, if it is slipping, just drive home using 2nd, 4th, and 6th (or 1st, 3rd, 5th). You should get more reliability than a regular manual trans, once it's all sorted, but it will be a few pounds heavier and likely still have more losses then a well managed stick shift.
