Certainly. I've been considering it. My cycling activity has gotten down to single track mountain biking (here in rural New England), loaded/solo touring one month a year out west, and utility trips to the store, etc. I could enjoy doing all of these things on a fat bike. Trouble is, I already own 3+ bikes to cover these functions, so I'm not too tempted to sell off two of them. But yeah, I know others who have arrived at owning one bike: a fat bike and they are some of the happiest riders I know.
