I just joined the GIS Forum. I hope this is the last GIS forum I join. Check it out here. I've also joined the GeoCommons.
And I'm about three hours away from having a fully-functioning (though license confused - using the 60 day trial until I figure that one out) ArcGIS on my new macbook. Read about how spanring installed ArcGIS. I basically did the same thing (with Parallels) but bought a copy of OEM XP SP2 from Tiger Direct. Also, Geolibre did it too, but in 2006!
