Diane Duane's books in her 'So You Wanna Be A Wizard' series have that problem. She started writing them in the early 90's and then continued the saga recently in the 00's.

There are certain incongruities in terms of technology. But you either understand she's trying to make the books culturally relevant for pre-teens and teens now or you miffle about ab Apple II becoming an iBook in what is really only a matter of weeks.
