Lets look at your arguments:

    "Why download every program you have to run?"

Why not download it?  On many (most?) PeeCee networks, the major apps are kept
on a fileserver and downloaded right now.  Besides, on a modern 100Mbps
ethernet, network transfers are nearly as fast as disk transfers.  NCs are
being targeted at the corporate market so the network infrastructure is
already in place.

    "PCs are cheaper"

Yes, but not cheap to maintain.  The sysadmin/computer (or sysadmin/user)
ratio tends to be higher in the PeeCee world than in the Unix workstation
world because a Unix system is easy to maintain remotely.  Of course you
can always run Unix on a PeeCee and have the best of both worlds :-)

    "PCs are more expandable/upgradable"

Straw man argument.  Many motherboards have onboard SCSI/Ethernet/Video
already ... what's left to expand except RAM, and you can certainly
add RAM to an NC.

    "Java is slow"

It doesn't have to be.  With JIT compilation or Java ASICs there is no
reason you can't get good performance.  But remember, the type of apps
that a typical office user needs do not necessarily require a high
performance machine (unless you use Microsoft bloatware as your
example :-)

IMHO, the NC is a good idea simply because it allows better use of
resources.
