I think it's particularly cool to get this chance to see Kit and Nita using the technology they would have been using if it had been around when they were actually that age and that inexperienced. They're still themselves, very much so, and the transition doesn't look strained. They're not tied to a decade, and I can't think of any plot devices offhand that depend on the lack of technology in order to work.

Though it's amazing how easy it is to get around cellphones these days when it's necessary to have someone be out of contact. I was waiting somewhere and the movie they had on was one of those creepy slasher (knife-guy, not the fandom kind) flicks, and the girl was baby-sitting and couldn't get in touch with any of her friends, because they were all at a wild party on a remote hill with very spotty cellphone coverage. The plot device devisor in me approved.
