Only if there is only on of the service. There is only one Amazon cloud storage, but there are thousands of other online storage places so switching is easy.

On the other hand there is only one IPhone, and because it uses coca switching is difficult.

2) Thousands of other online storage places I guess you simply pick you poison, er, locked down platform with various restrictions.
