Induction doesn't work for all pans, and require a 240v line run to your stove top. Combo washer/dryers take significantly longer to do laundry, since you can only have one load going at a time.

These are tradeoffs, and there's nothing strange about that. Personally, I have looked at getting both, but the cost and tradeoffs (given how my kitchen is already set up and the amount of laundry we do) just didn't make sense.
