There have been advances > certainly but they've been more evolutionary than revolutionary I consider the performance of the LiIon batteries in my power tools pretty revolutionary. I cut the plug off my main-powered drill and used it for something else. Compared to the first generation NiCad drills etc there is no comparision. Another area to look at is the LiPo cells in toy helicopters. I looked at an electric flying machine about 20 years ago as an academic research project, and it was basically impossible. Now they are childrens' toys. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
