Vista64 is very common already and Win7 x64 will be even more widespread. 64 bit CPUs have been there for ages and we should support them. Regarding the 64bit JVM I have to state that we should keep shipping the 32bit one - it still seems to be intended by Sun that 32bit java is used on 64bit windows: - The 64bit JVM does not install a Firefox plugin, or at least it does not work (maybe because Firefox is still 32bit?) - The auto updater of the 64 bit JVM installs a 32 bit JVM so then you have 2. This is obviously a bug but it shows that Sun does not properly maintain the 64bit windows JVM yet.
