Has this movie dated or not, from a technical point of view?

I watched this movie the other day on TV, for the first time since 2002. From a technical point of view, I'm wondering if others think that the movie has dated or not? I found that it has, but not enough to ruin enjoyment of it. A couple of areas:

1) Nobody uses landlines anymore, and I doubt criminals would even bother cutting a phone line today

2) A panic room in 2011 would almost certainly have an internet connection that doesn't rely on a phone line (such as cable, or satellite). It would be much easier to contact the outside world this way. I'm surprised that even in 2002, this wasn't thought of when designing the panic room, although the panic room could have been built before this was possible.

3) Having 1 individual CRT monitor per video camera is *very* 80s/90s (I always think of Scarface when I see this). These days, you could just have one large monitor and have all the camera images shown simultaneously on a single screen.

4) VCRs are obsolete - all recording now would be to a hard drive or DVD.

Other than these few minor issues, the movie still holds up well nearly a decade on.
