aviation software question

Posted for a friend of mine who does not have usenet access.

He's looking for software for his laptop that will give him charts,
hook to a gps, and read XM radios weather channel. He would like to
know what others use and if there are any glitches. He knows he can
get in the dash moving map but would rather have it on the laptop.
Aircraft is a Beech twin with full IFR, and the goal is to supplement,
BUT NOT replace paper charts, and maybe see some weather.
cost is a issue.

Suggestions ?

Thanks, Steve Roberts
