Edit: Long winded post warning....
People saying they cant see a need for this. Bear in mind back in 2001 we got broadband which ran at 1.8 mb/s and people were saying how thees no need for internet that fast and stuff LOL
Or 2004 when we got a dual 2.5 GHZ mac pro with 2 GB of ram and people couldnt get their head arround why we would need 2 GB of ram or 2 x 2.5 ghz cpu.
Now a £350 laptop comes with 2+ ghz dualcore + 3 GB of ram and the average speed across the u.k. is 5 mb/s
my (longwinded) point being is things change so you should be glad people are trailing 1 gb speeds so were ready for when its needed.
also above about the 1080p i'm sure there will be a new standard hd resolution a fw year from now, with screens getting so big now the resolution/screensize gap is closing in on old tvs
there are already videos on youtube shot in 4096p (I know that they were done with RED cameras whcih are pro, but thats how 1080 started off)

on the quality options click 'original'
It had to stream at 42 MB/s just to buffer slightly ahead of the video
