It looks to me like they removed a lot of features to get the price that
low, and fully featured laptops aren't that much more money.

We also don't know what the build quality is, how well Embedded XP runs,
what it will actually run (1GB is awfully small), etc.

What can you run on this thing?  Very little Windows software I know of
would run on it.

Any that you remove the hard drive from and use flash storage with?

The current Celeron should run quite a bit faster than a Pentium M.

Maybe you meant a P3 or P4 based Celeron?

ROM based OS are a little more resilient, but mostly because people
either never modify them, or because you can usually "reset" the system
to get back to a known state (which might also erase all your data).

Also, some malicious code targeting embedded systems has taken advantage
of non-optional events during boot to keep themselves alive, so
sometimes it can be a disadvantage.

What does it do exactly to enhance security?  Are you totally unable to
install drivers or OS hooks at all?

The vast majority of "build a cheap computer" projects end up with
really bad build quality, and that's what I'm talking about.

Not saying this one is, but I wonder what corners they are cutting.

The laptops that have come down in price are often being sold at a loss
to clear out old inventory, but plenty of them are also obviously
cutting back quality to reach those price levels.

I suppose we'll see.

So far I see a nearly 100% failure rate in this area, so I'm skeptical.

It's a noble effort, but the carcasses of past projects are all over the
place.
