why you need a book ? by that i mean that The books are going to be prepared by the resources that author will get from Sun. J2ME is field which is nascent field. So, you will put say $50 for the book & afterwards if you come to know that there is no content then it is waste of precious money which could have been used for other good things.
Since , lots of resources are made available by Sun officially. they are doing quitea good job. Palm has given free emulator to
test your application. So , you start with that. & then compare with the book before purchasing that whether it is giving concrete concepts or just superficial overview.
I think , I am quite clear now , by what I mean. Please tell me if somewhere I am wrong. As you said to learn new things , you will go for books. But what is the use if the book is not providing you the depth. That is what I mean.
My frank opininon is that People should be aware of the issues of new technologies & to know where the technology is moving. It is enevitable in the internet era. You have to be on your toes literally. I know people have personal problems. But ,that's life.
