I agree that PXE is a powerful tool/methodology for scalable systems
administration, although that isn't really orthogonal to a suitably
designed flashdisk-bootable system.

Exactly.  I have a 4GB Debian VM I run under VMware, and while I have
almost 9GB installed on my primary toplevel F8 system (including vmware,
not including the bootable images) the 4 GB system is actually more than
enough to do all the work I need to do.

Where I really look forward to "built-in" 4,8,16 GB systems is in two
places.

a) "Not-so-thin" desktop clients.  No hard disk to fail.  No need to set
up or manage a server for full diskless, or a terminal server (lin or
win) to run remote applications on.  Even 4 GB is enough for nearly
anything sane, and even a 16 GB flash is what, $100 extra in retail
price at this point and dropping fast?  16 GB is enough for a
kitchen-sink install plus 4 GB of personal home directory workspace, or
for a base system and a couple of fairly full-featured VMs plus
workspace.

b) Laptops.  I'd REALLY like a flash-driven laptop.  I'd like a bootable
OS on something pretty much completely shock-insensitive, preferrably
with some serious disk recovery tools for the data disk (if any).  I
drop my laptops from table height (so far onto carpeted floor without
any really bad result, fortunately) once every couple of years, and it's
just a matter of time before I lose a disk when I do it.
