title: Are these two 2008 & 2009 Dojo books hopelessly out-of-date/worthless?
body: <p>About 5 yrs ago I bought 'Practical Dojo Projects' and 'The Concise Guide to Dojo' (Wrox.)  But these 2008 &amp; 2009 books don't even mention which version they are written for.  I now have a project I want to do in Dojo. Are these books of any use today or will they just confuse me because of the major changes in Dojo ? Should I just wait (maybe 2 years or more ???) for Dojo 2.0 to be released ?</p>
