Microsoft has detailed how businesses who sign up to Windows 8 when it goes on sale later this year will be able to offer their staff a copy of Windows 8 along with the user's business apps, data and settings on a USB drive rather than giving them a laptop.
"When users insert their device into any Windows 7 or Windows 8 compatible PC and restart the PC, they get their entire personal environment, and operate as a fully managed device," Microsoft said.
As soon as the user signs out, the PC returns to its normal state.
The move should cut costs for any company that wants its staff to be able to access computers from anywhere without having to worry about issuing every employee a laptop.
It should also mean that taking your desktop on holiday is about to get a whole lot easier, as long as you have access to a computer when you get there.
The Microsoft Windows 8 Consumer Preview is expected to go live for consumers to download from today.
