I have been seeing these brushless motors and don't know about them. Can you tell me why they are better or why I would want one?

If you plan to buy a new drill, the brushless motor is the one to get. Its quieter and uses less power (so your batteries last longer). There are no brushes to wear out over time.

This is my first and I've only been able to use it a few times. The heft feels lighter/better than the 18v DeWalt I've been using for 10 years. One of the main reason I'm moving to this 20v model is because of the batteries. I keep 9 batteries in my truck and they are starting to wear out. The nicad batteries are not holding charge very long and the 18v lithium batteries are hard to find and expensive. A few months ago they released an adapter so I can use the new 20v batteries on the 18v tools. That works pretty well, so as my 18v batteries die, I'll be replacing them with 20v. Then as my tools die or as I find good deals on the 20v, I'll upgrade them piece by piece.

From a google search...

In a tool with a brushless motor, the motor adjusts according to the task. The more resistance a drill or saw senses, the more power it draws, and conversely a lack of resistance lessens the pull. This is a huge advancement when it comes managing battery life, which ups runtime and increases the performance of cordless power tools. A standard brushed motor will always max out on whatever speed it's set at. A brushless motor also does not have the friction or voltage drop that a standard motor deals with, which will increase the life of the motor and overall performance.
