The variability of clients is too great to allow enough optimization, and virtual machines (VMs) are too big to be quickly loaded and started on demand. This does not mean that there were no successes with Java on the client side. For example, there are applets that display continuously updated stock quotes that are quite useful and effective, but this is because they are very small.
