You don't read economic papers. Don't you? Or what is it with this
plumbing server/pc market around us? Or increased notebook sales.
(Typical marked saturation symptom, like the second car for the
familiy :-).

I suggest it's precisely the end of the open invention curve out there:

1. Nowadays the CPUs are indeed good enough for most of the common tasks.
WindowsXP tries hard to help overcome this :-). But in reality Win2000
is just fine for office work.

2. The technology in question is starting to hit real physical barriers becouse
it appears more and more that not everything comming out of the labs
can be implemented at reasonable costs.

Perhaps it's just still too deep in to my brain that
the overwhelimg part of the PC market is still determined
by corporate buyers (70%). And they look for efficiency (well within
wide boundaries :-). There is for example not much of an uprush from
Win4.0 or Win2000 to WindowsXP. Not only due to "political" reasons,
but becouse a normal PC from few years ago still does the job
for office productivity. Quite away from the days of yearly upgrades
all around the office :-)... And finally the whole thing driving
the movement behind AS/390 boxen running Linux OS instancies is consolidation
and costs too...
