Just how common has Java 5.0 become on the computers of average users? I’ve been trying to decide if I will target 5.0 or stick with 1.4.2 to minimize the need of updating for the majority of users.
I haven’t exactly been keeping up with how 5.0 has been accepted by the mass public, but I’m sure that you folks will have some helpful insight for me. 
Many thanks!
