Bob,
Freehand is a vector drawing program. From what I can see on the web, Gimp manipulates jpg types of graphics and doesn't offer the tools needed to produce maps from scratch.
Jim,
This is a bit off-topic, but the only reason I considered updating to Mountain Lion was to enable Apple TV. Then after purchasing the upgrade, I learned that it wouldn't work for older MacBook Pros (2011 and earlier). But, I bought the update so I installed anyway. Shame on me for trusting Apple and not thoroughly investigating. Shame on Apple for advertising this release with AirPlay as a feature and not highlighting the caveats.
I still love Apple products, but not as intensely.
Ron
