WTF do you people keep typing "Evaluation" for? On Microsoft's page listing the differences between a Technet and MSDN subscription they do not use the words Evaluate or Evaluation even once.. They say "use" a lot.. Then they specify what you can use it for. Technically, BOTH subscriptions are for the dictionary definition of evaluation of their software.
Examples::
MSDN: Become familiar and keep up to date with the latest Microsoft software to support your application development process.
So, you're allowed to evaluate their latest software in order tosupport your application development process.
TechNet: Become familiar and keep up to date with the latest Microsoft software to support internal or external clients using or deploying the software.
So, you're allowed to evaluate their latest software in order to support internal/external clients using or deploying the software.
See, they are different ways of evaluating their software, so it doesn't make sense for you to say TechNet is evaluation and MSDN isn't. If you want to get TECHNICAL, both of them are evaluation. They are not full licenses that never expire. However, in terms of what you're physically able to do with the subscriptions, with the exception of the free developer tools from MSDN, they aren't that differnet... (If you don't count price) -- Get a TechNet subscription and purchase Visual Studio. You'll be able to do the same things you were able to do w/MSDN.
