I have a turbo-diesel pickup. It's a Dodge with the Cummins. I can answer your concerns about them and anything else that you would like to know about them. I'm pretty knowledgeable on the subject.
As far as them being slow to respond, yes sometimes the throttle is a little less responsive then a comparable gas engine. This is due to the turbo. When you push the accelerator, the turbo has to have time to spool up. For it to spool up, it must have exhaust running through it. The time that it takes to do this is called turbo lag. So you have to give it a little throttle to spool it up, then hold on. Once the turbo kicks in, you have more then enough power. Now in todays turbo diesels, the turbo lag is very minimal. Mine takes about 1 second. Minute, but it is noticable. I believe that Ford's new Super Duty has dual turbos, which should cut turbo lag to almost nothing. I'm not a fan of the Ford's engine, but it's is just fine for people who do more road driving than pulling and towing.
As far as them being bad around corners, all trucks are bad around corners. They generally have a higher center of gravity so they have a good bit of body roll. Couple that with the very light weight rear end massive amounts of torque these engines create, and you have to go slow around corners to avoid tipping or losing traction in the rear. Especially with the 4x4's because they tend to sit a little higher in the air. It's not bad and very easy to get used to.
The main problems that I have with my truck are the huge blindspots and it's a PITA to park. You have to park at the back of the parking lots. Do you do more city or highway driving?
