Been really wanting native syntax highlighting support for awhile now, so these past few weeks I decided to implement it myself. I have a functioning Evernote client that has syntax highlighting and code completion for nearly a dozen languages. These include C++, C#, COBOL, HTML, Java, SQL, Perl, Python, Ruby, VB.NET and XML. It is very much alpha stages right now, and there are many issues that I need to work out, but I have been using it for a couple weeks myself. I can definitely keep you all updated as I progress with it if anyone is interested in using it!
