Why not? If you don't like it, just don't buy it. I could see myself getting one or two for stationary tools like the miter saw or wheeled tools the 6 gal. shop vac (it is made by Ryobi, but I have an adapter that lets me power it with Makita batteries). For those applications, weight is not nearly as much of a concern. I don't see why "boat anchor" batteries can't coexist with smaller ones.
