[CQ-Contest] Contesting with an Apple Mac computer?

[John WA2GO]

It's time for me to buy a new laptop computer. I need it for general every 
day use (Internet, Wordprocessing, Spreadsheets, etc.), but would ideally 
like to also be able to use it for contesting.

Are there any serious contesters out there successfully using an Apple Mac 
or Powerbook? If so, what are the options for software, and how is rig 
interfacing performed for radio control, voice keying and CW keying?

I have never even owned a Mac, but keep hearing such great things about them 
I thought I would give it some serious investigation.
