Handy, yes. Even for routine things like running a Dremel tool.
But portable TVs, portable DVD players, laptops, all can be run directly from 12V dc-to-dc converters, which are more efficient than using an outboard inverter to make 120VAC, which is only dropped back to 12VDC inside the electronics.
It is easy to wind up figuring that you need a 1000W inverter (after the Dremel comes the power saw) and while you're at it, a true sine wave design so it keeps electronics happy...and then, inverters aren't so cheap anymore.
