Watching the videos the lack of luggage space is an issue. We pack light, but more than a couple of backpacks.
The number of seats is a bigger issue. While the kids are grown I occasionally fly one of them with us, plus Angel Flight mission and planning on doing Young Eagle flights too. Last year I flew the middle daughter and her two medium sized dogs down here for a vacation, and then back home. This summer we're taking our oldest and a friend of hers up to VA. They are doing a bachelorette party, we'll do our thing there that weekend, including touring Monticello.
Too often I need more than two seats.
I think the plane is neat, but just don't know how it would fit my flying. Maybe if I had it as a second plane. I can't see my wife going for two planes though.
