Re: Important iTools 6.5 and Jaguar Information

[Paul Willis <paul@xxxxxxxxxxx>]

Hi

A good point if it is true but as far as server purposes if the Apple 
sales message for 10.2 is to be believed....

.....seems like a good reason to upgrade to me.

....and as all new Macs are shipping with 10.2 now it will be hard to 
avoid. While we don't plan to upgrade our current G4 towers we are 
going to 10.2 when our Xserves arrive.
