Saw brakes. Both Bosch (outside the US) and SawStop have technology where a current in the blade can detect the resistance of something that isn't wood and throw a brake before the blade can damage your hand. The Bosch one doesn't even break the blade, though the SawStop one does. The patents are still snarling it up, but it'll happen eventually. Also, accuracy and precision on smaller/cheaper tools. I have a "jobsite table saw", which is a thoroughly budget one by comparison to a big ol' cabinet saw. And being a smaller saw has a lot of problems, but one that stopped being a problem is a rack-and-pinion fence even on fairly cheap (~$300) table saws that provides really, really solid accuracy.
