No doubt they have some nice features.  They also lack some I consider
essential.  I don't think we're going to reach an agreement on what a
good price/performance ratio is.  Perhaps you get a bigger paycheck or
are happy with the same PC for longer than I am.  I spend around $400 a
year to upgrade my PC (new mobo, CPU and RAM, occasionally an additional
amount for a larger HDD) and easily double my performance every year. 
With a Mac I'd have to shell out $2000/year to maintain the same
situation (and given their glacial processor improvements *if* it could
be done remains questionable).  To me that's unacceptable in today's
commodity PC market.

Everything.  The fonts are AA by X (Xft extensions), but the desktop is
AA by the video driver (nVidia), which, IMHO, is where it ought to be
done (most modern video cards support fullscreen AA in hardware).  I'd
be surprised if Apple doesn't leverage this same hardware support.

But at least they *can* be sent across the network <wink>.  I've done
little research and it appears that Apple's remote desktop is very
similar to VNC or PCAnywhere.  It isn't possible to run a single app
remotely - you run the whole desktop and share it with anyone who
happens to be at the console: you move your mouse, his mouse moves. 
Contrast this with X where I can run a single app on a remote PC while
someone else does something else on that PC without interfering with
each other at all.  Undoubtedly Apple figures this type of thing isn't
too interesting to their target market (and perhaps they'll add it
later, if their architecture allows) but to me it's an essential aspect
of my computing environment.  I have 4 PC's here at work, one in another
room, and I routinely run monitor apps, editors and whatnot remotely.  I
can run GUI apps on systems that don't have a GUI running, which lets me
use graphical configuration tools on our little P133 Linux firewall
which isn't able to run a full GNOME desktop.  My gf runs XMMS remotely
off of my home PC so that mp3's (all legal, I swear!) get played over
the good speakers (which are hooked to my PC) instead of her little
laptop ones, etc.  I can't imagine settling for less.
