In the end, only you can make that decision. Personnly, I could never see owning a truck or SUV that wasn't a 4x4, but that's because I use it and live in area where I have access to trails. Plus the occasional winter blizzard makes it even more handy.

If you're not much of an "outdoors person" (i.e. hunting, fishing, camping, mountain biking, etc) or don't live near any trails, farms, mud or whatever, then no, you probably don't need it. Don't get a 4x4 because it's "cool", get it because you think you'd like to get to places a 4x2 can't take you. And keep in mind, you may someday want to venture West or East and visit some destinations that are ripe with mountains and trails. But again, only you can make that decision based upon your needs, lifestyle, etc.

That being said, yes, go get a 4x4! You'll love it!
