I disagree on this point. It's been the rule of thumb for years now. But almost everything runs modern switching power supplies now and they don't seem to care very much about the square wave power that cheaper inverters put out.
I installed a Xantrax Freedom HF 1800 (square wave inverter) in my Georgetown about a year ago. Since then I've run everything on it for many hours without trouble. The old Westinghouse TV did give a quiet buzz while running on inverter but it ran that way for hundreds of hours that way without failing.
The tube TV in back, the PS3, the DirecTV sat box, microwave, AC Fan (for keeping cool on mildly hot days), laptops, Cell phone chargers. None of them seem to operate any differently on square wave then they do on PSW.
If you can afford a PSW inverter go for it, there is no down side other than the cost. But it's not worth the extra money to me.
P.S. I installed a very large battery bank, which is why I can run the microwave. Don't expect to run the microwave unless you do a lot of extra work.
