Some longer term players, will use delayed data as they are trading longer
term, and dont care too much so if the orders were delayed a bit more,
these players most likely wouldn't care/notice.

But also you have to consider, there are a large degree of shorter term
players, who are in/out of the market and play both sides, these do have
real-time data feeds, and do care about latency. Some shops go as far as to
only use a certain length patch cables from their trading PC to the switch
port they are connected to. Also consider when news releases are announced,
the markets often do move quite fast, and a LOT of money can be made/lost
in seconds, so delaying the orders, could and would affect the outcome of
the trades.

Also consider that a vast majority of the trades are automated by
computers, and some want their servers setup as close to the exchange as
possible, in fact the CME group released that they will offer/lease data
center space:

"One such project is a 428,000-square-foot data center in the western
suburbs of Chicago opened by the CME Group, which owns the Chicago
Mercantile Exchange<http://topics.nytimes.com/top/reference/timestopics/organizations/c/chicago_mercantile_exchange/index.html?inline=nyt-org>.
It houses the exchange’s Globex electronic futures and options trading
platform and space for traders to install computers next to the exchange’s
machines, a practice known as co-location — at a cost of about $25,000 a
month per rack of computers."
