Lowest level coding doesn't neccessarily mean 'simple',
but it can avoid delays like useless paranoid protection
and weird code detours given by HLL-abstractions.

Yeah, and I think at least hardware drivers should be written at lowest
level, even windoze may have problems with direct hw-access.

True, beside that a GPU can act as busmaster on accellerated AGP
which is not available for the VESA-aproach.
So even a plain write to screen will be up to 8 times faster than VESA.

When I look at latest mobile phones, with TV, internet, VideoPhone,
games, mass-storage, USB, and whatsoever else functions merged into
one? mass-production single chip, then the future is today already ...

Low cost mass production may try to combine all into one chip, but
I think separated units for sound, graphic and math will remain for
high quality demands.
[interesting future image...]
I also see many little independent CPU-cells with their own memory,
but with several (light?) busses to share with neighbours and masters.
So almost a tiny network of little PCs ...

yeah.

I can image that my housekeeping android fry me breakfest eggs in
front of me. And it would 'nice to be near' during winter too. :)

This reminds me of something, ...mother nature already invented this ;)
I hope androids will once cost less than my former wifes :)
For future power issues I'd pray:
'may Lord Light be on our way and protect us!'
