Touchscreens can serve a function. And that's predominantly when you have your laptop atop your lap. In a cafe or on a plane where even operating your touchpad may be hard for a lack of space (or for me size of gut). On the couch is another scenario like that. If you don't encounter those situations a lot, don't get it, especially if it's more expensive. If you hate fingerprints on any screen, don't get it. If you're not sure and money isn't an issue, take the extra feature.
