Proxima's Lightbook

It weighs just over 11lbs (5.2kg) and fits into an attache case: the Proxima Lightbook LB20 looks like the latest step forward for people who have presentations to make on the road.

Proxima, based in San Diego but with a European HQ in Marlow, has tried to make the LB20 as versatile as possible. It takes input from PC or Mac computers, accommodates a variety of video standards including NTSC, Pal and Secam, and is equipped with a power supply unit that will work in the US or Europe. It has its own speakers and amplifiers but can be connected to external speakers.

The device is about the size of two notebook computers when it's closed.

In use, the top half swings up and forward to reveal the lens. There is a control panel on the top but Proxima also supplies two remote handsets, one for frequently used functions and the other to add mouse functions, on-screen annotating and highlighting.

The lamp, at 400 watts, isn't as bright as on larger projectors, but one reviewer found it good enough to do the job even with the lights on.

The lamp has a life expectancy of 40 to 60 hours, and the unit has room to carry a spare.

One complaint: in the US, Proxima is quoting $4,999 for the LB20; in the UK that has translated to a suggested retail price of $7,495, a 50% increase.

The LB20 is available from Proxima Europe on 01628 481555.
