My problem is that I am invested in vim to the extent that I will need to relearn quite a bit if I give up vim. I can do that but what does ST provide me over vim - that's my main point of debate along with the fact that the $70 price for one version with paid upgrades means things are not in the impulse purchase zone over the long run. (Not upgrading doesn't really work - ST2 might stop working if I upgrade to say Ubuntu 14.04 and I am not sure if ST2 will continued to be supported and how long.)

I would have bought it if it was $29 and proprietary OR $70 opensource donation ware or $49 proprietary with 3 free version upgrades. That's my comfort feel around editors - YFMV of course.
