It's also mostly purely practical. PHB's rarely listen to the technical
justification for more hardware. They even more rarely understand it ujntil
it's translated into financial terms (i.e. this new server stack can deliver
the  400tps we need to support the anticipated sales growth of our online
store  -vs.- This new server stack will simultaneously save us $2k/month in
power and cooling while also allowing an anticipated potential increase in
sales of $500k/mo)

Once it's personal for them, they sign the PO immediately.

Also, always make sure the assistant/office manager person has a seriously
screaming fast machine. Hers (usually female but sometimes male executive
secretary/assistants) needs to be some serious hardware and rock solid
software 'cause she's the one keeping him (PHB in 200x is _still_ usually
male but that is changing) on-track and moving and that requires instant
access to all the information he can't be bothered with (between tee off
times and where the next 3 martini lunch is and which board member hates him
and wants to replace him with the board members wife and who got drunk at
the party and said...).

Practical evil has uses :-)
