[Ham-Mac] OS X advice

[KD5NWA]

I just upgraded my 8600 with a 800 MHz G4 card and 256 Megs of extra 
memory, and I need some advice.

This is a stopgap measure, as I plan to buy a Dual G5 within the next 12 
month to be used as my main computer at home, and relegate the 8600 for 
Video/Photo editing purposes.

Which OS should I have for running the most number of Ham applications, 
should I stay with OS 9.1 or should I upgrade to OS X ?

I own a copy of  OS 10.1 should I upgrade to Jaguar or wait for Panther if 
OS X is the best choice?

Would Yellow Dog Linux be a consideration?

I have a Dell Laptop also but I would like to use the Mac when possible.

Thanks for the bandwidth.
