After actually reading the articles, I am still unclear about two things when your subscription expires: 1) How long will I have access to my documents? According to current documentation for enterprises and small business:
When a subscription is removed, all data is permanently lost.

What happens to my documents if I am using 100% of Skydrive (including the additional 20GB)? Is there a grace period? They don't make it easy to find the information to these questions. The answers are likely the same for any other cloud service that provides a free and paid offering but why do we have to guess.
From: http://www.zdnet.com/microsofts-office-365-home-premium-what-happens-when-subscriptions-expire-7000010498/ "For users with an Office 365 Home Premium subscription, as the expiration date of that subscription approaches, users will receive notifications inside the Office applications and via e-mail to remind/nag users about the approaching expiration date. Once the subscription expires, the Office apps will enter a "read-only reduced functionality mode." This means users will be able to view or print documents, but won't be able to create any new documents or edit existing documents. Users who want to regain their full Office capabilities will be able to purchase a new subscription (via Office.com) or a set of predesignated retailers. Users also will have the choice of simply using older, existing versions of Office or to just use the free Office Web Apps on SkyDrive for basic editing. If a user has stored documents created/edited with Office 365 Home Premium in their SkyDrives, these documents will still be downloadable once subscriptions expire. Users can save SkyDrive documents to another computer or drive at any time, according to Microsoft. (With Office 365 Home Premium, users get an additional 20 GB of storage on top of their existing SkyDrive quotas.)"
If you wind up with the same packages, you're doing it wrong. The reason to compile from scratch is that you can tell the compiler to use optimizations appropriate for the processor you're using.
Have you done profiling on any packages built with all those ultra-specialized optimization flags to see how much it actually benefits you?
Further to this, will you ever get back the CPU time it takes to compile ?
I have a theory that it's impossible to prove anything, but I can't prove it.
