Part of this rapid hardware replacement cycle almost certainly had to do 
with the rapid growth in CPU capabilities in comparison to software.  
New classes of applications and capabilities were opening up just as 
fast as CPUs would allow.  Many network appliances use embedded 
processors based on the same chips used in desktops or laptops of 
similar vintage.  They run custom software and may have additional 
dedicated chips.  Thus the development of the FrankenPix and custom 
Linksys wireless router firmwares.

Today even a 3(+) year old machine can do a fine job running office 
tasks (given enough RAM), whereas in the late 90s/early 00s, a three 
year old PC was not likely to be able to run the then current software 
very well.  Today CPUs have progressed so far ahead of most software 
that we're able to combine multiple systems into one through 
virtualization and still obtain good performance.  Tasks formerly given 
to dedicated chips (RAID, sampling rate conversions, compression) are 
now commonly done on CPUs and GPUs.

I also recall articles/webpages/blog-precursors talking about how many 
packets a particular CPU could route per second.  The articles might 
have been in relation to building custom Linux based routers and router 
hybrids (such as router-bridges, adding QoS, etc.)

I feel that recently many changes in information technology have become 
less revolutionary and more evolutionary as we look for the reasons to 
build newer/faster/stronger/better equipment.  The rise of netbooks as 
low CPU/GPU power machines underlines the evolutionary changes.  The 
next series of revolutionary changes are still waiting in the wings 
(compact/portable devices, realtime 3D, gaming, scientific, and 
rendering applications are still pushing the envelope).

I know organizations where equipment refresh/purchase cycles have been 
stretched from 3 years in the early 2000s to 5 years now, as they've 
observed both a slowing in need for the latest and greatest, as well as 
this being a response to budget pressures.  Replacement periods are 
becoming less based on technological obsolescence than on equipment 
failures and end of warranties.
