Looks like Mac OS X 10.4.1 is available
"According to reports, Apples bundled iLife applications, major
selling points for the Mac operating system, are already Intel-native and run
at full speed... Given Apples experiences with software piracy, particularly
the rampant software piracy that spread developer builds of Mac OS X 10.4 Tiger
all over the Internet this past spring, Apples management from the top
down knows full well that this developer preview will be in the hands of every
kid with a cable modem within days of its release. Most of them will be able
to install it on their own computers and run it and the full suite of iLife
05 applications at full speed, and run most existing Mac software in translation.
As a result, Apple will give thousands, possibly millions, of people a taste
of Mac OS X running full speed on their own PCs. Apples giving their potential
future customers a free taste, thats what theyre doing. Its
a try-before-you-buy deal," Harrell writes.
