I've got three of them (or let's say my wife and kids have them... and the donkey...) I ride,.... but not my particular cup of tea... I'd rather watch them peacefully graze the pasture from the man cave windows or from the pool with a cold Sam Adams...
They are however, a great animal with the kids and my wife. 4H projects, and some real nice folks you will meet along the way.
Unfortunately, the comment about having two is correct. They are a herd animal an they get very "uppity" when left alone and no-one pays attention to them (like when you are at work, kids in school) and they get lonely.
If you ride them, you must ride them - alot -... or you end up having to "break them in" to riding all over again. And, as mentioned..... it's not the horse that's the expense... it's the saddles, tack, feed, supplement, trips to the vet, shots, farrier visits every six weeks, etc. Proper care is the issue as mentioned. First name basis with your vet & farrier is a must...
It's really a commitment - more so than a "hobby". "Horses For Dummies" from your local bookstore or Amazon is a must if you have never had horses.
In the kingdom of the blind, the one eyed man is still just the bus driver....
