I guess almost all the people who will 'deploy' Win 8 are the less technical home users who get it pre-installed on a new PC. A few home users will upgrade from an earlier OS.

I imagine that if other business's Proof of Concept testing went anything like ours did, very very few businesses will consider an 'upgrade' to Win 8 due to the enormous productivy loss, extensive retraining requirements, increased helpdesk calls and application redevelopment costs.
