Denny,
I think the reason behind x10 wanting your
home control computer connected to the
internet is so you receive all available
updates to the Activehome software as it
becomes available. And in future updates
to the software, you'll be able to control
your activehome equipment from any internet
connected PC, such as while you are on
vacation or at work...instead of just from
your home control computer.
I agree with arf1410 that the software is
quite functional and easy to use. It's
really the reliabilty of the hardware that
my complaints are about.
