Well, it's fairly common in any large corporate environment for software to have to be approved from the top down. Everyone runs OS Z until it's worth the expense to upgrade to OS Y. Makes support issues far easier to handle.

Yup. It's easy to forget that when you are a single user who would really like Feature X.

I really feel like PC functionality has hit a plateau. Especially in the current economic environment, it seems like it would be much harder to justify PC hardware/software upgrades if you are running stuff that has been acquired in the past 2-4 years. For general business use, what situation would demand upgrading a 733 Mhz processor? For what purposes would OS9 *not* suffice?
