When using wp_add_inline_script, a CDATA section is required if you need your document to parse as XML (e.g. when an XHTML page is interpreted as XML) and you want to write literal i<10 and a && b instead of i<10 and a && b.
This is not an issue with scripts that are stored in external source files, but for any inline JavaScript in XHTML you will probably want to use a CDATA section. Note that many XHTML pages were never intended to be parsed as XML in which case this will not be an issue.
