i keep wondering ... how those loaner accts work ...
- is it the same config as the system being bought and
is it a comparison ot the other cpu ( all else being the same)
- loading one's own apps on loaner accounts can become tricky ...
- best to get the boxes inhouse .. even if its 2-4 of um for testing
and you know you loaded your stuff on it .. and can now do a fair
comparason and benchmark

they're pushing and the buyers know what they're getting

always best to use rackmounts ... looks fancier :-)
