Vacations? Travel the whole United States first, then start with the rest of the world from there. If you really have an unlimited income . . . I think it would be interesting to travel the whole world.
Cars? I'm fine with my cadillac, I'll consider buying something new when it breaks.
Homes? Nothing special.
Hobbies? Same. Internet, reading, writing, video games, etc.
Charities? To be honest, I wouldn't think of it unless someone brought it up or it was a charity I was directly effected by. (Family member having a disorder/disease)
Other Expenditures? I'll think on it.
