Yeah but memory is dirt cheap and it's now almost a decade ago 64bit x86 CPU's were introduced. The beauty of 64bit is that many operations which had to be broken up in composites on 32bit (i.e. on long and double) can now be done in one go by the JVM. This has performance impacts but probably more importantly, it means operations on these are atomic and thus thread safe - not having to spread locking or volatile directives around ones code or be an expert on the Java Memory Model, could be seen as a desirable trait.
