I got my first one because it was the only way to book flights online at the time. But now there's visa debit and all that so need for them anymore.
I got my first one years ago in the early 90's for similar reasons. Using it to book holidays etc... But now that Visa debit is about, as you say, no need to get credit cards any more.
That is a piece of advice I always give the younger members of the family. Never, ever
get a credit card and buy things you don't have the money for there and then.
