The line launcher looks cool, batteries have come a long way and the tools are adapting to the different jobs better as time goes on. Milwaukee is pretty good, they seem to be the favorite in construction, but I'm a big fan of makita. I have a bunch of rigid stuff too, and i like them a lot too. I still personally prefer corded tools for most things tho, batteries are nowhere close to the durability and functionality in crappy environments. I've been in steam vaults working where the batteries get too hot to work, very annoying fighting your tools when in an environment like that. The grinders are still no where close to comparable yet, and i like using a 9" for most stuff so no way. We have some 6 and 4" milwaukee ones at work and i pretty much refuse to even use them anymore, good for a small quick job but when you're doing heavier work they simply can't keep up, and have no torque compared to a wired grinder.
