10 years ago I was firmly in the "GA would be a waste of my time because I'm too used to flying fighters and it'd be boring." I was wrong. It's not as challenging as flying fighters, but having your own airplane is awesome. I had a Glasair for a few years and I've had my Bonanza 36 for 6 years now. I still fly it more than 150 hours a year.
The older I get, the more I like airplanes - all airplanes. The year I started at Delta I was flying the Eagle, my Bonanza, A-4's at Draken, 757s/767s at Delta and started on warbird T-6's. I just like airplanes. My wife loves traveling in our Bo; hates commercial - even non-rev in first class. For some destinations, GA is where it's at - Bahamas for sure. I'd say don't knock it till you try it (renting one for the weekend isn't trying it). GA isn't for everyone (nor is the airline) but they both suck a LOT less than I was expecting.
