You're going for the sarcasm, but that's really the only point I see for these mega speed tiers. I do a lot of Android hacking and regularly download ROMs in the 300 to 700 megabyte range. When I had my 10Mbps connection that meant killing 10 or 11 minutes of time while I waited for it to download. Now I can do it in 2 or 3 minutes, which is certainly nice, but it's hardly a fundamental change in the way I use the internet.
I currently have the luxury of mooching off a business class symmetrical connection (30/30) which has completely spoiled me. It's dedicated speed and has more upload than any consumer grade connection I can obtain. When I have to go back to a residential line I will miss that upload more than anything else. I can't match it where I currently live (TWC, 50/5 is the best here) or where I plan on living (Cox, tops out at 150/20 and is totally out of my price range, the most affordable tier is 50/5).
Frankly I'd rather have 10/10 or 20/20 with good contention ratios (i.e., I should be able to count on getting full speed most of the time, barring exigent and/or unforeseen circumstances) than one of these overpriced mega speed tiers that offers shitty upload with massively oversubscribed download.
