For a home user it is not all that much of an issue, if you are running a remotely recent OS then it is probably already IPv6 capable. At worst you may need to replace your modem/router box, and those who would have trouble with this are likely to be with an ISP that takes care of such matters for them.
When you are dealing with large scale infrastructure and corporate networks however, things become a little more difficult. At that scale the assumption of running a recent OS doesn't always hold, so you have software updates to worry about which incurs at least a time cost (and time is money). Also the possibly replacing your router becomes replacing racks worth of managed switches, routers, dchp servers and so on. That's not even beginning to take into account all of the legacy software that expects IPv4 and requires it in order to work.
So, yeah. Simple for home/small business users, but a major project for the IT guys who make things work behind the scenes. Fortunately said tech guys should have been working on getting ready for this for a while already; just like when they made sure that the world didn't fall over at the turn of the millenium.
