What Apple is doing isn't in the least bit unethical. The company isn't being intentionally deceitful or misleading in any way. Tiger has received a significant amount of press (for being an unreleased title), and Apple has an entire section of thier website devoted to the next-generation OS.

I think it's time for people need to start taking responsibility for their actions and stop trying to blame others for their silly mistakes. We live in an age where information is so readily available it's rediculous. You no longer have to sift through magazines and library books for knowledge, just do a simple search on the internet and you'll probably get more info. on a subject than you ever wanted. We need to stop expecting people to hold our hand and guide us through every little decision we make. Capitalism favors consumers who take the time to evaluate the market and make the best choice.
These educated consumers will conduct a little research prior to making significant purchases. These people likely know that Tiger's release date is nearing, and will delay their purchase if they deem the upgrade beneficial or necessary. As someone else mentioned, some prefer to use the mature version versus the latest and greatest (and sometimes buggy) version.

Granted, there are instances where corporations take advantage of consumers just to make a quick buck. The fact that this occurs is quite annoying and unfortunate. I simply cannot see how Apple continuing to sell their current OS while their next OS is being prepared for release falls under this category, however.
Disclaimer: The above rant wasn't directed at anyone on this forum. It's just a general observation/frustration that I have had as of late.
