Not at all. I generated a key for a win7, a visual studio and an office on the day that I got the account and that's it. I've been using the virtual machines on Azure though. Kept a Linux machine up and running all the time. But that didn't even eat half the monthly credit that comes with this type of MSDN.
Other things to note is that I received a couple of standard emails from Microsoft Reps welcoming me to Bizspark and asking me about feedback and if there's anything they can do to help me out with whatever troubles I may be having. But I completely ignored those emails.
