Dell has shown off a pocket-sized (though somewhat bigger than most USB sticks) device that works like a thin client.
"Thin clients" which are cheap terminals connected to servers which run the software you need.
This rather enigmatically named Dell device, called Project Ophelia
, lets you do the same thing, only instead of needing an actual computer you can use a TV or monitor screen.
The business traveller's best friend? Plug the Dell USB into a TV or monitor to turn it into a basic work station.
The idea is you can open your work documents over the Internet without using a laptop or tablet.
There is a bit of a catch - you need a TV or monitor with an MHL (Mobile High-Definition Link) port.
MHL-equipped displays are available from Dell and other vendors including Samsung and Sony.
The device uses Bluetooth for communication with a mouse and keyboard (which you'll need) and Wi-Fi for Internet access. Power is drawn from the monitor or from a separate USB socket.
Project Ophelia is designed to work with virtualisation technology from Citrix, Microsoft and VMware.
The gadget is expected to be available before the middle of the year.
