I am setting up a Eclipse 3.2.2 development environment for applications that will be eventually deployed to Websphere 6 and 7.  I narrowed down my choices for the J2EE server to Geronimo 1.1.1 and Websphere CE 1.0. 
I found lots of information saying that Websphere CE is *based* on Geronimo, but no details on what is different.
Can somebody please point me to a comparison between the two?
