The Trek should serve you fine for communting arond/light trails. I would also look at what Giant has to offer if you are willing to change brands. Giant is usually pretty goood about giving you a lot for your money. If you ever decide that you would really like to get into mountain biking, don't cheat yourself out of a good experience on the trails - you will find much better performance in terms of real off-road riding by going a bit more expensive. For sommuting, though, it seems fine.
