> Java programs normally sit on a server, or many servers of the same arch. That's true right now, but it wasn't true in the recent past (SPARC) and it might not be true in the near future (ARM). Early in my career I was on a team that migrated our Java application from elderly Sun boxes to newer x86 hardware, and it was relatively painless. There's a good chance we'll eventually to the same from x86 to ARM. Most developers will also continue develop on x86 for the foreseeable future.
