That Husky video is one of the worst I've ever seen. Never got a good look at the saw.
I'm all for an electric cordless saw. Anything new is expensive at first. Only 15 yrs ago a good plasma TV cost $20,000. Around the same time I paid about $5,000 for a computer that could do hardly anything compared to my current $199 phone. The saw price will come down, and it will get better.
I use my Husky corded electric a lot. Not practical as a climbing saw, but I sure never wonder if it's going to start. Cuts as good as my gas saws and doesn't have that chainsaw sound (when I want to be discreet). Almost all my small tools now are cordless, drills, sawzall, etc.
Just a matter of time.
