I would get that one, its a good deal and will make you a fine commuter. I commute on a hardtail 26in with suspension fork, slick street tires, and I built it all up myself with all the comforts of home to my liking. I do not have any bounce at all on the front suspension and 26in wheels are great in traffic where you need to accelerate quickly at the green lights. The 29er or 700c is larger in diameter and will accelerate slow and doggy on a MTB. Ok on road bikes though. The lower gearing will be nice for the hills and expect to go somewhat slower overall but the ride will be more enjoyable and the upright position will afford you to see better around you and also be safer. Just remember to not be in a hurry and allow yourself the time to get to your destination because you do work harder on a MTB in comparison to a lightweight road bike.
