Believe me, I get it. But these battery-powered saws are more capable than you can imagine. And you can't really see the benefit of one until you use it a few times. For average work, cleaning up snags and average size trees... the convenience is really hard to beat. No mixing fuel. No pull-starting. No deafening noise. Just pick up, pull the trigger, and cut. When you're done, put it away and don't worry about ethanol gelling up in your carburetor. Is it going to be running in 30 years like a tried and true gas-powered saw? I highly doubt it. But that's the trade-off. There's no replacement for gas saws when there's serious work to be done. But your average homeowner doesn't need that kind of power.
I own a 40-volt battery powered ice auger too. Will it be running in 30 years like all those 2-stroke gas augers of yesteryear? Probably not. But man, today, right now, it blows those gas augers clean out of the water. More power, more torque, no noise, no smoke/fumes, starts every time, AND it has reverse (incredibly useful for flushing slush from a ice hole). I might be dead in 30 years. So I'm going to use whatever tool makes my heart go pitter patter today.
