given how clamped down rapidshare and other file downloading is I don't see the need to brag about speeds anymore, anything for me at least over 5 megs doesn't make a huge difference... but here it is. Having unlimited bandwidth would be more useful in the case of people with netflix and the like.
I reside in both Canada and Michigan and I always test from Michigan locations as it is more accurate and is faster. Though it isn't ever consistent on which site in Michigan I test with. After all you are just pinging to a host that can be as legit as a local news station or community college.
