Batteries are nice but they introduced an issue that you did not have with corded. With corded you could buy the best of the best period. With cordless you can buy the best of the best but only from the battery platforms you own unless you buy into a new battery platform. Would be nice to have "universal batteries" any brand of battery fits any brand of tool. Kinda like what Fein and Bosch tried with Starlock on OMT's.
