title: What's the advantage of using Zend Developer Solution over Zend Studio?
body: <p>Got a call today from sales and Zend and they were pushing the Zend Developer Solution (bundles Zend Studio and Zend Server). Since I'm with a start up the cost is an issue, and the developer solution is almost twice as much as just buying Zend Studio. </p>
  
  <p>The sales person told me that with Zend Developer Solution you will be using and testing "Business Grade" PHP.</p>
  
  <p>Can anyone tell me what this means? If you have experience with both, please let me know your thoughts on whether or not there's a big advantage for a relatively small dev team (9 developers)</p>
