"Ending sentences with a preposition is something with which I will not put" is a quote often attributed to Winston Churchill, but is probably incorrect: http://en.wikiquote.org/wiki/Winston_Churchill http://en.wikiquote.org/wiki/Winston_Churchill It's one of my favourite examples of the tortured tangle into which we twist the language occasionally, in order to comply with seemingly arbitrary grammar rules. However, I instinctively cringe when I see sentences that end with a preposition. I don't know whether this is learnt behaviour, but I really do find the constructions for which the preposition is accounted earlier in the phrase to be more elegant. The alternative to your example would be: I'll come (or arrive) after I have finished writing this reply. I'd argue that this sentence is less folksy, but forces you to be more precise about your intent and action. I often find that when writers resort to poor grammar because they lack the attention to detail to state exactly what they mean. This is especially true as we move to faster and faster paced methods of communication in which precision is often sacrificed for a speedy, less clear reply.
