The Optoma Pico Pocket Projector PK101. Just the right thing for teachers who've had to break their backs and strain their arm sinews carrying bulky multimedia projectors to their classrooms. But for many, this pocket-sized gadget may be too big for their pocketbooks. And some may eventually realize that what they want is not what they really need, or, to put it another way, that what they so feverishly dream of may not be what really matters in their waking hours. Or that, at times, sourgraping may actually be good for one's well-being. :)
