While I would love for any readers to help support this site by using the Fix Your Thinking affiliate link below, I hope that the majority of you will wait at least a month to install it on your Mac. Give the blogosphere and Apple News Internets some time to report on the problems and for Apple to release at least one update.
Tiger STILL has issues - as there have been 10 updates in 3 years since its release. (We are currently at Mac OS 10.4.10 in case you aren't keeping up.)
I would like to stress that it is VERY important that you at least have Mac OS 10.3 (Panther) by now. In my day to day job of Apple consulting ... it is very difficult to support 12 years worth of operating systems. Some of my customers still use OS 9. While it took until Panther for me to permantly switch to OS 10, I haven't looked back in over 3 years. Not until a few days ago had I even booted any computer into OS 9. (I had to in order to play Bugdom on an older iMac DV.)
I usually go to Atlanta (about 100 miles away) to attend the launch party of each OS (I went to the Jaguar, Panther, and Tiger launch parties ... no launch party announcement has been made as of yet.)
Back when Tiger was released many people got their AMAZON.COM shipments a few days early. This would possibly be an advantage of ordering from the link above.
Mac OS X 10.5 Leopard requires:
* minimum of 512MB of RAM
* any Macintosh® computer with an Intel, PowerPC G5 or G4 (867 Mhz or faster) processor.
I wonder if this includes or excludes Dual 500's and Dual 800's?
