I notice that for most people, it's still a big question what are the most important differences between 32-bit and 64-bit. I hope this table will help you understand why 64 bit os better, and why it doesn't have to be that more expensive.
This table was actually an extension to my previous blog, where babrown already summarized what is actually in it for NAV customers... .
See my comment to Waldo's previous blog. Remember you're dealing with financial systems people. They understand things in terms of "what will it cost me"
This is very good. But the question I remember always hearing is: What's in it for me?
