Yes, definitely -- this is true for many use cases. Not all by any
means, but enough that binary packages are a must-have.

Now this I dispute absolutely. Whatever gave you the idea that
generating and maintaining an archive of binary packages was at all
"simple and straight forward?" It is most emphatically neither of those
Firstly there's a matter of the scale of the job -- the ports contains
around 23,000 different software packages. That's pretty respectable
compared to most Linux distributions, remembering that there are several
hundred packages' worth of stuff in the base system which would have to
be packaged in a comparable Linux system. Most of those software
packages are under active development, and virtually none of them are
prepared to alter their release schedules one iota to suit FreeBSD.
Just keeping that collection current is a huge task, let alone trying to
maintain and improve the system used to do it.
Then there's the small matter of compiling all that software to produce
the binary packages. At the moment there are 3 different major OS
versions supported across two Tier-1 architectures (i386, amd64 --
everything is expected to work on Tier-1) and four Tier-2 architectures
(ia64, sparc64, powerpc, pc98 -- which should be supported for package
building, but only on a 'best efforts' basis) plus maybe 3 or 4 other
experimental architectures like arm and mips which have the potential to
become very important in the future as they are the basis of a lot of
embedded computing devices. And people have the temerity to complain if
updates aren't available online within a few days!
To support all that takes some pretty impressive computing power spread
over three different data centers (I believe), all of which has been
*donated* to the FreeBSD project, and all of the power, cooling,
bandwidth, maintenance and other ongoing hosting costs are similarly
supplied by donation. Not to mention a hard-core of about 20 key ports
committers, plus maybe a hundred-odd other committers taking a more
peripheral role, and some 4,000 other volunteers that do the work of
All of this elides one of the insanely great features of the ports --
which is how configurable and adaptable they are. The trouble is, the
design of the ports really does work best for compiling from source.
There is functionality there which is somewhere between "incredibly
difficult" and "simply impossible" to push up to a set of pre-compiled
binary packages. (Which, by the way, is a feature common to all binary
packaging systems: you always get whatever someone else thought was a
good idea at the time.)
The ports really are one of FreeBSD's crown jewels, and as a system for
compiling software from source and installing and maintaining the
results it has few peers. It is certainly true that FreeBSD's binary
package management could be better. Binary package management under
FreeBSD has always been seen as bit of a second choice compared to
ports, and consequently it has not had the same sort of development
effort put into it. Until recently, that is. We have literally just
had the announcement of the beta test version of the new next-generation
binary packaging system on the freebsd-ports at ... list earlier today.
Don't get too excited though -- it will be months at the very least
before pkgng goes into anything like production.
