The hell you don't. You use every available resource for every flight. That means the radar that you're looking at on your display as well as radar from your computer.
As far as the time lapse. You would know what time the radar was updated, it's timestamped. It would be one more tool in your bag. When faced with a decision to deviate around an area of weather, left or right, wouldn't it be nice to better know what lies ahead for the next few hundred miles beyond that?
I'm sure I can't be the only one who has ever decided to deviate one way, only to realize that you got yourself stuck behind a line that will take you even more off course.
Edit: In addition...when you call dispatch to "get an idea on the weather" what do you think they're looking at?
