The wining of many of the people on this list make me laugh. I heard the same thing from the Novell, SNA and AOL users about IPv4 and the Internet.
As for the business case, here are five reasons to move:
1. PERFORMANCE - Performance browsing to an IPv6 enabled server is 10-20% faster, making anyone's web properties look better to their customers!
2. LOWER COST - The maintenance of IPv6 networks cost 17% less, then IPv4 only or dual stack.
3. BETTER SECURITY - IPv6 end-to-end communications along with DNSSec with DANE, perfect forward security, BPKI, and others. Reduces the chance of man-in-the-middle attacks, SPAM, and identifying source of DOS's.
4. MAINTAIN COMMUNICATIONS - If your mail servers, web server and browsing is on IPv4 only, there are website today you will not be able to access.
5. GROWING MARKET - No matter what your business, the network effect (Metcalfe's law n^2) allow you to connect to more people, and systems.
