How to download SQL Server Developer Edition?

 was planning to download a trial of SQL Server Developer today from MSDN Subscriber Downloads. I have two questions: Next to each download it says: "No product key is required". I assume this means that a 28 day trial is initiated after download? What is the difference between SQL Server Developer; SQL Server Web Edition and SQL Server Business Intelligence? I assume that SQL Developer can do everything that SQL Server Business Intelligence and SQL Server Web Edition can do? I followed these steps: Went to the appropriate MSDN Subscriber Download page Selected: SQL Server 2014 with SP1 x64 Logged In Saved the file locally During the installation select "Evaluation" rather than the license key. To my surprise, there was already a license key populated. I have an active Bizspark account (though I did not renew in year three). It must be this account that has populated the license key. Why is Enterprise Edition evaluation installed rather than developer edition?
