Hi rzm61, it's not that you can't use a BMX bike to get around, but it's really not meant to be a commuting bike. Better to get something like a MTB for a commuter, and put slicks on it so you can go faster. You don't need a full suspension MTB either, a hardtail would work just fine.
How hilly is the commute? How are you planning to carry everything you need with you?
