I don't have an MSDN subscription but can get an Office 365 developer subscription for $99.
For $8 per month, I can get an Office 365 Enterprise E1 subscription.
So these 2 options come out to similar cost.
It looks like I am able to deploy a developer site with the Enterprise E1 subscription.
So my question is, why would I ever pay $99 for the developer subscription when I can just get the E1 plan and deploy a developer site?
Am I missing something here?
