After I got my SCEA, I then moved to PHP, Adobe Flex and iPhone development!
Seriously, I still spend majority of my time working in
Java (part of my time is spent on the things mentioned above) but the company I work for is relatively small and they don't care what credentials you have as long as get the job done.
For now, my SCEA is just a line in my blog which somehow adds a little "authority" to the things I say in it.
Even if it has little value in itself in my career, I still think that taking SCEA is a good learning experience.
