Here is a subject every one is talking about Simon Sabin http://sqljunkies.com/WebLog/simons/archive/2006/4/10.aspx has mentioned it. He has a link to Steve who has created a great Q&A about it http://blogs.msdn.com/stevelasker/ .
At the moment some of the details have not been finalized. But the Q&A shows what our thoughts are we are actively looking for feedback..
SQL Everywhere is not a new product but is the SQL Mobile edition product with the limitation to the mobile platform removed.
