That's my personal opinion, and I realize that some of the commercial
vendors may care about their insane customers' satisfaction, but I'm
simply not interested in insane users. If they have that much RAM (and
bought it a few years ago when a 64-bit CPU wasn't an option), they can't
be poor.
From our perspective, the main issue is that some of these machines we spentquite a bit of money on the big RAM (for it's day) + lots of 15k RPM SCSI drives + multi-year support contracts. They're highly IO bound, and barely use 10-20% of their old 2.4Ghz Prestonia Xeon CPUs. It's hard to justify junking those machines < 5 years.
