- D2 looks and feels foreign to me as a somewhat D1 experienced user
- Templates maelstrom and strong emphasis on them
- D1 grew organically, D2 looks like an academic exercise where stuff is put in just for the sake of it by the people that don't write programs in D at all (Andrei)
- D2 book and Andrei are a filibuster for D2
- Walter Bright listens to Andrei (ok, a smart guy) but he doesn't write D programs, I doubt even Walter writes them (seriously). If you look at his code, it is more of a C in D than D code.
- I have little to no trust in DMD/OPTLINK, LDC/LLVM is what I'm after and that front is D1 only, and looks like it will be
- Lots of people smarter than I am are on D1 also (Tango, namely) - and I don't want to go against the trend since it would isolate me from little support I can get
these are just of top of my head, there are more. General summation could lead to "It just doesn't feel right" - at least for me as a heavy D1 user.
