With the release of Windows XP, at least three issues will constrict the client-side Java market.
===== first ===
The default security settings for the latest beta of Windows XP classifies applet class files as being untrusted. Feel free to register your protest.

===== second ===
The default Web browser would require that software be installed by novice users in order to support applets *at all*. Hence the call for OEMs to pre-install the plug-in. Consider adding your signature.

===== third ===
Applets that use the plug-in generally specify the version of the JRE that they require. So a user will eventually be prompted to install multiple JREs. But no mechanism for incremental upgrades exists. There's no reason for a dialup user to have to download the entire 7+ megabyte JRE to upgrade from version 1.3 to 1.4. Hence the call for a mechanism for incremental upgrades. It could use your vote.
