awesome!!!!Jaguar may have all the speed and features, but those interested in Mac OS 10.1.5 need look no further than the local Apple store.
"All of the new display iBooks have 10.1.5 installed," reports one Apple retail employee via telephone.
"We've had more than a few Apple fans get pretty excited after discovering this."
The new 600MHz and 700MHz iBooks are still shipping to consumers with Mac OS X 10.1.4.
Apple has declared the minor update the last refresh before the introduction of the next major Mac OS X revision, codenamed Jaguar. Recent internal builds of 10.1.5 are reportedly "ready for primetime."
Notable changes in 10.1.5 include faster iDisk access and Quartz anti-aliasing in Carbon applications.
