I have felt having one platform would be a great thing but it doesn't work out. Currently I have Bosch 12v, DeWalt 7.2v, 12v, 14v, & 18v. Dremel 12v, Hilti 14v, Makita 18v, Milwaukee 4v, 12v & 18v, Ryobi 18v, and Stout 18v, not to mention the other various lights and other rechargeable tools. That's a lot of batteries and chargers to keep track of. The last couple years I have been trying to cut it down to just Milwaukee stuff. I'd love to sell off all the DeWalt but some things would be expensive to replace and not all are available in my preferred platform.Glad you said it and not me. I never really understood the mindset of only one platform. Now I wouldn't do a bunch but I have most all of the 20V DeWalt stuff but started to buy some of the festool battery line. I'm not going to toss the things DeWalt but if someone has something battery powered that makes sense for me to buy, I will.
