Last week, I walked into my local Sam’s Club to find a 1200-lumen Epson PowerLite S1 digital video projector selling for just 950 bucks, and it was small enough to fit in my briefcase. Sure, dramatic drops in the price of techno-gadgetry are nothing new, but the speed of this decline was supersonic. Two years ago, it simply wasn’t possible to get a small, bright, high-resolution projector for less than about $3,500, a hefty sum for a device that most trial lawyers won’t use more than a few times a year. So, we borrowed from colleagues, paid high rental prices or just did without, because only the big cases justified the trouble and expense. No more. Now we can afford to buy one of our own systems and use it all the time.
