I hardly consider 32 bit architecture a 486.
Some are unable to afford cutting edge technology, as well as having a little patience until the bugs are worked out. Like everything new, it will be a learning process and mistakes will be made.
I think what ISS says makes a lot of sense, and have basically followed his philosophy. I never buy the latest technology, I don't think there is much value in such a purchase. I seldom use beta versions, I prefer things working properly the first time I install.
You cannot expect software companies to immediately respond to new technology, it is costly to do this, and they have the obligation to first service the majority. Both CloneDVD and AnyDVD have responded to those requesting 64 bit support with their new Beta versions, these folks are dedicated to customer satisfaction like no other that I'm aware of.
