It's tough to stay on topic with this. Any aspect of it is going to invite comments on viability, practicality, etc. That's a tiny step away from "off topic".
I think "cordless" is being over hyped and oversold to consumers right now. I work at a big box store and it's painfully amusing how may customers absolutely have to own the latest cordless tools. Im the salesperson. I own lots and lots ( and lots) of tools. But the only one I prefer to be cordless is my drill.
I'm not a contractor. I do not make my living with my tools. For contractors, by all means, the best cordless tools are necessity. For most homeowners they are a really stupid waste of money. With the cost of battery replacements and the six year cycle of battery/charger technical obsolescence (and backward compatibility at the whim of the manufacturer) most homeowners are getting raped. They can do 99 percent of the same work with an extension cord, and a corded tool that will never be obsolete as long as 120vac is available in your home. You'll hand a perfectly good tool off to your kids instead of landfilling it. I still regularly use my inherited 25 year old Milwaukee sawzall and my even older craftsman miter saw.
For the contractor, this steep expense, and disposable tooling, is a write off. For the homeowner, it's mostly idiocy and keeping up with your neighbors idiocy. And it's hyped hyped hyped by the major brands as total necessity.
