Does NXT have any unique plans that cannot be solved easier on the more flexible Ethereum platform?
Indeed.
1) Smart Contracts -- Not Turing-complete but covers basically 99% of all smart contract problems (trust me contract writers do not need Turing-completeness)
2) Automated Transactions -- Turing-completeness addition to Nxt; for the 1% other applications that require more elaborate algorithms
Btw. more flexible is not easier. In fact, most of the time it is the other way round. With more flexibility comes a steeper learning curve and bigger amount of mistakes made.
I hope you realize that there is NO END to feeding the Ego... make sure to tell Come-from-Beyond too...
I am sorry, this is not about ego. This is about being pragmatic and I do not see why we cannot have parallel solutions.
Of course, Turing-completeness means that it can do everything one could possibly do and therefore includes the functionality of Smart Contracts. However, the pragmatic approach right now is to have Smart Contract to cover the majority of the pressing use cases.
After that, Turing-completeness will handle the outstanding use cases.
