Cool!  So do I!  :-)

I have an 800 MHz computer and a Sony 900 MHz baby monitor!

I have not had a problem with the monitor, but I did note that AM
radio went to hell!  (listening to the NPR news station is almost
painful).

I did notice that at work the problem was greatly reduced (I used to
have this same computer at work) because I have a huge Faraday cage,
AKA big metal desk, which surrounded the computer.  I am guessing that
you might achieve similar results if you get a steel desk.

Usually, I can go upstairs (with the computer downstairs) and the
static (on the radio) is greatly reduced.  (I sometimes use a laptop
as a remote terminal upstairs).

Here is another suggestion.  Put the baby monitor in another room and
turn the volume way up.  This is how I have addressed the AM radio
problem.
