Everyone needs to stop complaining about Leopard supposedly being released too early. Every company, Microsoft, Apple, etc. all do it. I have had hardly any issues with 10.5.0 or 10.5.1. My only issue is Disk Utility and permissions repair, but that isn't a huge issue. It still does what it is supposed to do and will get better in time with future updates.
People keep comparing Leopard to Tiger. Does anyone actually remember 10.4.0 (or 10.0, 10.2.0 or 10.3.0 for that matter)?? Personally, I thought that 10.4.0 was much less stable than 10.5.0. Tiger didn't get into it's prime until around 10.4.3+. And you guys have to give Apple credit here. They are having to compile a pretty much universal OS that works on both PPC and Intel.. that's no easy task. Tiger's 10.4.0 debut was only for PPC only, and then they had to port and separate them at around something like 10.4.6(?) for Intel processors. Leopard is different, it is totally universal, it has to be able to run both, which requires more code and will take longer to update and debug, but they are getting faster and more proficient at it. Give them time. A lot of the stuff people are complaining about (driver issues etc.) are not directly put out by Apple. They are often made by other companies (ex: Nvidia, ATI etc.) with Apple input. Give it time. If people are so unhappy with Leopard, then go back to Tiger until 10.5.3+. No one made you upgrade. I for one am very happy with Leopard. I think it is the best OS they have released yet. Like someone posted before, not all of their testers will be able to test the OS under the way we each uniquely use it. That's why Leopard asks you to submit bug reports when something happens, so that the OS X team can examine what happened and what caused it. If it's quirky behavior, submit a bug report manually through apple's website. Just give Apple time, they are busy at work on improvements and aren't just sitting on their duffs saying "oh well, sucks to be you".

I'd much rather get the OS 6 months earlier and deal with the issues that come along with being an early adopter than have to wait another 6 months. For those of you who don't want to deal with these issues, NEVER buy anything until the 3rd or 4th version is out. It's quite simple!
