We're old enough (unfortunately) to remember when laser pointers were new and expensive, not the kind of bargain-bin item you can find at OfficeMax. But even though they've become surprisingly affordable, we've been disappointed at the preponderance of that make little or no sense.
That's why we appreciate the "Jasper Keynote." It's a laser pointer with a built-in radio transmitter that can let you point and run your PowerPoint presentation simultaneously if used with a USB receiver. And the best part of all: It's green (our favorite color).
Thanks to I4U News, we also learned that the human eye is roughly 50 times more sensitive to green than red. There'll be a quiz in the morning.
