Since I'm a user of the XM product, I'd be

As a user of WSI's in-cockpit weather, I am under the impression that XM
NEXRAD can be up to 10 to 15 minutes old, depending on refresh rate and time
it takes to assemble the NEXRAD mosaic and transmitted up to XM's satellites.
If that potential for stale radar data is indeed true, then using XM (and
WSI) to weave one's way around intense thunderstorms is false security.
