    Just thought this brings today's technology into perspective.

    (quote) Projection technology has come a long way in five years!

    It's been five years since my first multi-projector review, and the differences between that inaugural class of projectors and this year's review crop are simply astounding. Back then, the maximum native display resolution was VGA (640x480), now it's SXGA (1280x1024). In 1994, the average desktop projector weighed between 25 and 30 pounds. In 1998, the average weight is under 18 pounds, with some portable models weighing less than 10 pounds.

    But the biggest change is in the performance. Five years ago it was a big deal to get more than 150 ANSI lumens from an LCD projector. In fact, even the brightest boxes of '94 were hard-pressed to do much better than 400 ANSI to 500 ANSI.

    Today, the 8.3-pound Sony VPL-SC50U can produce 500 ANSI without breaking a sweat, while desktop/boardroom XGA projectors from Electrohome, In Focus, NEC, Mitsubishi, and Sanyo have blown by the 1000 ANSI barrier. Contrast has improved considerably, as well. In 1994 I was impressed to see a single- panel LCD projector generate 50:1 or greater contrast. Today, 100:1 is considered ho-hum. (unquote)
