When I first installed Leopard it ran great, a few small bugs here and there, but it was fast and stable. Over time it got a little worse, but nothing that really bothered me. Now as of today it's gotten so bad it feels like I'm using Windows. Safari constantly crashes on me, probably like 5-8 times a day at completely random times and the website I'm at doesn't matter. A lot of the time when I'm doing something simple, like clicking on something in iTunes or iWork, it will freeze and I will get that spinning beach ball thing for like 20 seconds. It will either start working again or crash. It happens to all my programs. I have no idea what to do about it. I'll probably end up reformatting this weekend. I barely made any system changes. Only thing I ever do is occassionally download a new program from apple.com, but those can't be the problem because they are from Apple, and I got so few from there.
