They were already migrating from the big iron vendors like HP, IBM, and SUN for such undemanding needs. Most of the big retailers had centralised data stores, and would stick say all credit card transactions to a central server. They would have a hot spare, as they wouldn't want downtime, for obvious reasons. Even then the PCs would sit with minimal load until the January sales ;-) Okay credit card transactions are generally pretty small in terms of data capture. But we all too easily forget just how much oomph modern computers have.
