Showing your corporate slideshow to a single person on a laptop is fine, but if you need to project your Powerpoint presentation to a larger group of people, a larger image (to project your own large image) is in order. If you need to fill a conference room wall to strut your stuff, NEC Technologies thinks its new LT75z and LT150z Go! Series projectors might suit your needs without causing you back strain. The LT75z and LT150z give you a projector/PC remote, manual zoom and focus, and a presentation viewer. They also let you download presentations onto a CompactFlash card so that you don't need to lug your laptop around with the projector. The LT75z and LT150z weigh 3.3 pounds and offer SVGA and XGA native resolutions, respectively. Both provide a light output of 1,000 ANSI lumens and a 700:1 contrast ratio. The LT75z and LT150z are now available with estimated street prices of $2,335 and $3,325 respectively.
