Chicago is pretty expensive for public transportation. A monthly pass is $75 for the L and buses. A commute from the northern suburbs is $100 a month for Metra trains and an additional $30 per month for buses and the L. There are discounts for people that qualify.
The price and the poor schedule to northern suburbs makes it unusable for me. It's great for weekend trips to the city.
For many people that's true, especially if you don't need the Metra pass. I'd consider it if the stops to my station were scheduled more often. The bar car is gone from the Metra, but they still allow alcohol so you can relax, have a drink, and listen to music.
