Looking for Mapping Software (for mapping data not for GPS)

[PALong3]

I presently use MapPoint to map data for consulting clients when analyzing markets. I switched to MAC from the world of PCs about 6 months ago and still have to maintain my PC for this sole purpose. I have searched but have not found a mapping software that gives me the flexibility to map territories and different data for presentation to clients.....Is there one that I haven't found beyond the standard GPS software and Google Earth?

I have enjoyed the world of MAC - but quite a hassle to tote around my MAC and then have to also take my PC when on the road...

A quick google search suggests that there is no equivalent for OS X. You might consider using vmware or parallels to avoid carrying around two computers.
