Thing overheard in STAR TREK line

No Spoilers. This was overheard at in the line to see the new 2009 Star Trek.

I was entertained by the new movie last night, premiering on IMAX. (I'm always temped to type that iMax these days)

However, I'll be honest, I was also highly entertained by the line chatter of the nerds and geeks and trekkers and trekies in the line around me. I'm a big fan of other people's conversations in a situation like this. Nobody debates and argues like a good Trek fan... except maybe Mac vs PC arguments.

Overheard (paraphrased):

But the Enterprise has a universal GPS system.

> Well, if you want to use that word... it's hardly GPS. I mean, it's not satellites.

It's big anyway... If it uses the starts, it still works like a GPS, telling them where they are.

> The Navigational Computer.

I think that calculates routes, not where they are.

> A GPS does both.

They had a whole room for navigational positioning in Voyager like it was something new.

> Whatever... The enterprise has always had a map of the universe.

They're going where no man has gone before.... I think they're making the maps.

>Right... and sometimes they trade for maps of new areas. Neelix knew a lot.

So it's all the same computer? How come it goes down with everything else? When the computer core goes down, they can't navigate. That';s dumb. Doesn't each computer have enough on it's own? A GPS fits in my hand.

>But a GPS has one city or country. The universe is big.
>Besides, it's in the Canon. One computer for everything. They use terminals like the old days.

How come when they eject the core, computers still work?

>Different core.

I think each desktop could handle it all.
Maybe they will in this movie.
