Which would you say is better the "group of people" or the "hardware and software"?
I can not say one is better over the other because there is no way to compare.
Perhaps I am not following your question correctly.
Maybe if you stated why you are asking. I can understand how to answer the question better.
I've lived in the states all my life and I don't claim to have good English either. As long as I can understand and possibly help, It doesn't matter about spelling or bad English.
OEM versions of Windows 7 come with brand new PCs (from the likes of Dell, HP etc...). They are a license type that works when you buy from an Original Equipment Manufacturer (OEM).
MSDN (Microsoft Developer Network) is a group that technical professionals can join (for a fee) which lets you download many MS applications and license it through that.
Neither is better or worse, they are just different ways of acquiring a Windows 7 license.
Thanks Ian - I think you stitched this one up - I have not heard a version called MSDN before, That had me confused and not sure how to answer the comparison question
