No. I’m not going to talk about UMPC. That little tablet is cool but expensive. :-).
So, let’s try something smaller and inexpensive.
That’s “portable software” +
Portable software’s are software, which doesn’t
need to be installed. I mean, you click on the exe file and program
works right away. Whenever I reinstall windows, it is accompanied by
the works of installing old programs again. So, I keep all portable
programs in a folder to use after installing fresh windows.
The point is that, if you put these programs in a USB drive, you can
plug it into any computer and use them without installing on that PC.
The best part of it is FireFox browser. You know, when you surf
Internet on someone else PC, you left all your footprints there. So
just use your own copy of portable Firefox
from your USB drive and leave that PC as if untouched.
Actually, there are many programs with installer, which can be regarded
as portable. You just take a copy of installed folder and use it
without installing later. In that case, Photoshop is portable; Opera is
portable and many other more. Try it yourself!!! ;-)
Oh, we are still using OS of host PC. Why don’t we run our
own OS. There are lots of Live CD
Linux distros. (I love Knoppix!!!) So insert your live CD and
run that machine on the fly.
DSL is damn small that it fits in 64 MB
USB flash drive.
are USB flash drive, USB Hard Disk drive (including mp3 players with
HD), USB zip drive, etc.

And here are some more useful links for running Linux from USB.

I just tested QEMU-Puppy
(Linux), which is launched inside windows. Everything
works automatically with QEMU and there is nothing to handle UNIX
things. (But, I think it’s not as good as KNOPPIX. Running an
OS inside OS is too much load for CPU and RAM.) Here is how
from USB Flash drive. (I haven't tried it yet.)
