In an aggressive change to its lineup, Panasonic this morning unveiled its LB75 and LB80 projectors for frequent travelers. The entire line is designed to be small and light enough to accompany a notebook, weighing under 7 pounds, and in some cases to have an almost cable-free setup process: the LW80NTU, LB80NTU, and LB75NTU all include built-in 802.11g Wi-Fi that allows them to deliver images from as many as 128 nearby wireless computers, including more recent systems running Mac OS X Leopard and Windows Vista. The designs are also more dust-resistant than earlier models and have better image processing to improve viewability in daylight.

Headlining the releases is the LW80NTU; the projector is the lone widescreen model of the group and outputs at a native 1280x800 that matches many notebooks and is better-suited to 720p HD video. It outputs 2,600 lumens of brightness and carries inputs for both PC and traditional video sources.

Other projectors fit a standard-ratio 1024x768 view. The LB80NTU makes up for its lower resolution with a higher 3,200-lumen brightness, while the LB75NTU supplies the same image at 2,600 lumens; the LB80U and LB75U offer the same brightness as their NTU equivalents but shed the wireless feature.

All but the LW80NTU ship this month at prices ranging between $1,999 for the LB75U and $3,200 for the LB80NTU. The widescreen model arrives in July at a $3,499 price point.
