The combination of the dramatic improvements in battery technology in the last 10 years or so and brushless motors (lower energy use and increased reliability) seem to really have been a game changer in cordless tools. It's like the change from traditional tungsten filament to LED bulbs that has happened in my adult lifetime. The little light in my cell phone is substantially brighter than the enormous 4D-cell battery Maglite that I used to own.
