I had one of the Bosch drivers, back when it was sold as 10.8v. The original was 1/4" hex only and single-speed. (400rpm IIRC)
I worked in the assembly area back then and used it for hardware attachment. It was fine for that, but useless as a drill. It required drill bits with hex shanks, which weren't nearly as common back then, plus being too slow.
They introduced a new model with a drill chuck and 2 speed transmission in something like fall of '08 or early winter of '09? It still had the same problem that still exists to this day. The battery is somewhat triangular and is installed backward (IMHO). If you reverse the tool in your hand, it feels much better. They also had a 90 degree version, which I bought too.
Then I discovered the CXS. It can do all of the above, realistically at a lower price, since it's all in one. I sold all of the Bosch stuff to co-workers.
