No, it isn't, because Kevin rashly made an absolutely categorical
statement that 'Only users on really slow connections' benefit from it.
You don't need to know what speed my personal internet connection is to
know that 3MB/sec (that's mega*bytes*, remember, internet connections
are specified in mega*bits* - 3MB/sec is 24Mb/sec) is a hell of a lot
faster than many internet connections can manage, handily contradicting
his assertion. Yes, my desktop is very fast, but so what? Kevin's
statement wasn't conditional upon system specs.
(My connection is actually specced at 25Mb/sec, but it rarely manages
that to a Fedora mirror; I usually get about 8Mb/sec for package
