Mass High Tech is reporting on a new virtualization startup, currently in stealth mode, who is readying a public launch in the field of ‘laptop virtualization’ (for lack of a better term).
Update – per their blog: they’ve launched.

The software would be designed to isolate a laptop’s four major components — hardware, operating system, applications and user data — and create versions on the laptop of those components that operate remotely, without a network connection. The software would operate transparently for the user and it would enable wholesale security updates and other types of upgrades when connected to the network. Isolating the portions of the system enables it to limit access to work-related applications while enabling users to install their own personal preferences on the device.
Virtual Computer (blog) is targeting laptops because that segment is growing faster than stationary desktops, according to the company.
