Intel has mentioned that this is the future. Intel is very security conscious and I'm sure they will be forcing a home IT build with VPN access along with what they have already, PGP disk encryption. In the future, I'm also sure Remote-wipe will be part of the process.
For the employee, this allows them to choose the laptop that suits them
For the employer, it allows them to push a partial cost of the laptop to the employee. What will be burdensome is the fact that IT will have to support so many builds and hardware.
So I guess, initially the employee will be able to purchase a few subsidized business grade laptops... I'd definitely buy a heavily discounted Thinkpad ;-)
Think about this... All business files/documents are stored in a data center under the employers controll, only to be accessed via VPN, or LAN (on employer's site)...
