If you believe some of the things written about Leopard in the past week or so, you may consider it the buggiest system upgrade ever! But, as with all things of this nature, that impression is a huge exaggeration.
During Leopard’s first weekend on sale, some two million copies were moved as retail upgrade kits and preloaded on some new Macs. Since then, it’s fair to say hundreds of thousands of additional copies have probably been shipped, and the vast majority of Mac users who have Leopard have installed it.
It’s also a certainty that any point-zero release will have at least some annoying bugs. Some of these issues were pushed aside in the rush to ship the product — though Apple would never admit that. Others were simply not granted a sufficient amount of seriousness, couldn’t be duplicated or weren’t anticipated.
So you can bet that, sometime in the next few weeks, there will indeed be a 10.5.1 update, and that, every couple of months, further maintenance updates will be delivered. This is something you have to expect, and you might feel angry at Apple for not shipping a more robust product, but the fact of the matter is that most of the Leopard early adopters have had excellent upgrade experiences, and I can be counted as part of that number.
