Yep, I just forwarded that.

Yep, I saw that too.

I'm probably going to go back to my previous instinct, until the 9500S
has been out for awhile, it's probably safest to stick with the 8506
series.  Just don't do RAID-5 on it though.  ;-ppp

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
