[Elecraft] Windows vs Mac

[Paul and Sue Huff]

Please forgive me for a slightly off-topic post but I know that the collective 
wisdom of the people on this list can give me a lot of good advice.

My shack computer is getting a little "long in the tooth" and I am starting to 
research a replacement machine.  My current ham usage for the computer consists 
of logging and some digital work, but future rig control could be something that 
I would be interested in doing.  Recent experience with a new iPad has created a 
very positive impression for me regarding Apple products but I know that "in the 
old days" most ham radio software was designed for Windows only.

So my question is this - Are there now good choices available for ham radio 
software (logging, digital, rig control) that will run on OSx computers?

BTW, I know that Linux is a popular operating system for ham radio these days 
but I don't really know anything about it.  I can certainly try to learn, 
however the computer has other uses in the family and so I would need to be able 
to easily switch it back into it's "standard" manufacturers configuration for my 
wife who is even less techie than I am.

Any and all opinions would be appreciated.
