What is Bitcoin's locktime feature and what are some example use cases?
And how can a user make use of this new feature? Is it in any gui wallet? And how would one use it in the command line if its the only option?

Like a cheque with a date in future, a Bitcoin transaction with locktime cannot be unlocked (read cashed) before that date. The definition in bitcoin.org is pretty clear
Part of a transaction which indicates the earliest time or earliest block when that transaction may be added to the block chain.
Sample use case is a cautionary deposit. For a great example see micropayment channel protocol implemented by bitcoinj and described here:
