I think learning Latin is totally worth it! I'm student teaching this fall as I finish up my degree in Secondary Ed with an emphasis in English. I plan on starting Latin this summer, although I know that it will take me at least a couple of years to master it. I agree with Paul; knowing Latin, or at least having an understanding of it, helps us to better understand the English language. So many of our words come from Latin, Greek, Old and Middle English, in addition to other tongues. By understanding these languages, we can dissect the English words, therefore strengthening our proficiency in English.
I want my students to master the English language, and I can help them accomplish this by helping them to understand roots and affixes. English is a fun language to play around with, and understanding the morphological patterning of modern English words helps to empower students as they gain proficiency and confidence in reading and writing.
I'm not recommending that you run off and study etymology, but I am encouraging you to at least gain a working understanding of Latin. You'll be glad that you did! As a bonus, it will make learning Spanish and Italian a piece of cake! HaHa!
