user3029: Since you can lend / lease you nxt to another account. 
What are the pros/cons of this nxt lending feature? 
What are some use case scenarios?

user15355: Leasing gives the other account your forging power, without giving them the ability to spend your coins. The two main use cases are:

To lease to a forging pool run by someone else. This avoids the need for you to run a server 24/7, and the pool should forge more often, smoothing out the peaks and troughs in forging income.
To lease to a forging node run by yourself, but on a machine you don't trust; for example a cloud service. You keep your balance on a secure machine and lease it to the insecure one.
