I got out of road bikes as well because of comfort issues. I got a hybrid and have been very happy, but it does depend on you. If you go down to one bike, you'll find yourself loving it much more, rather than being split between two bikes. You could try selling your Trek. See if the Schwinn is good enough for all purposes, and if it is you can always invest the extra money in some nice panniers or a trailer, or something else.
