Having a home cinema projector on hand can be useful at times. If you don’t want a massive TV in your living room all year round for example, or you don’t have the space for one. But they can be expensive, and unless you are going to get regular use out of it, probably not quite as good value for money as your TV in the end. But what about the portable projectors that are currently available?
The devices can be a compromise, offering you a way to bring a temporary home cinema set-up to your living room typically for less than it costs to install a permanent projector and screen.
