Google's Android also may be a blow to J2ME (and Java standardisation in general), but I wonder if it picks up. It will either be a Google stand-alone effort - and that is not of little relevance - or need endorsement from general phone manufacturers - so far it seems only Samsung joined in.
Well, J2ME does have the endorsement by virtually any manufacturer - the APIs are agreed upon by the big phone/device manufacturers after all - and I agree that it is well defined, but Sun may have missed something along the way ...
That said, J2ME is still THE standard for developing Java apps on constrained devices. And if you look at the JCP site, you'll see much effort has been devoted to it. Comparing the number of JSRs by platform you get 83 for J2ME, 44 for J2EE and 43 for J2SE.
