just to add - we lose our hydro power here on a regular basis, and my
tower has crashed a fair number of times in consequence. I have not
had subsequent problems. Is it possible that the effects of a crash of
this type are exaggerated?
I think I will be unclipping my laptop batteries from now on.

It all depends on at what point in the procedings the power fails.
Generally, if the hard disk is in the middle of a data write operation, that
operation is unlikely to be completed. Exactly what effect this has
depends, of course, on what was being written at the time. If it is some
bit of user data, then that data may not be available after the outage. If,
on the other hand, it was an important system file, then effects may vary
from some part of the OS not working properly to a system that will not
boot.

If you lose power regularly, then consider a UPS. If you search on the net,
you can find some very good UPSs that are sold for less money than could buy
just the battery for.

Yes UPS are really nice. You can also plug in other low power devices
like your cordless phone too, so they still work when the power goes out.

And yes these netbooks are really slick. Many are realizing that they
don't need anything else. Also it is hard to believe they can pack
everything in such a tiny box, eh?
