From TFA: "he denied that there is a widespread feeling that it is better to wait for Service Pack 1"
I'm not sure who might be saying that they are not waiting for a service pack before Vista deployment for their business. It's certainly none of the people I've been speaking with. Due to the number of problems with application compatibility, the problems with Vista itself, and the nearly non-existant benefit to my business that Vista would provide, I will be waiting for SP1. At the time that SP1 is released, more time will have passed so that our application vendors will have re-written or updated their code to match Vista's changes. We'll also have less of an expenditure for new equipment to meet Vista's hungry requirements since we're constantly retiring older computers and purchasing nearly top-level systems to replace them. We will _not_ be transitioning to gain access to any new "features" that Vista provides, rather, we will transition because we can no longer buy computers with XP installed. Even though Vista provides some positive enhancements to application/OS separation, we have found that user education is vastly superior to feel-good allow/deny prompts that an uneducated user will botch every time. It's more work, sure, and would be a significant effort with a company larger than our 90+users, but the savings come in time. The "trusted computing" and DRM features within Vista allow _much_ greater control of the computer to be given to the software vendor than any reasonable sysadmin would be comfortable with. Due to these concerns and others, my company has been exploring a move for all users to Linux and MacOS. I know of several other 100+ employee local companies that are doing the same.
