I could itemize, but several people already did, so I'll add a different perspective. Some products are so much better that, when you try them out, you realize there was a quantum leap there. Like when I tried a capacitive touchscreen phone: it was obvious Nokia style phones were deprecated. Electric traction is just like that. Obviously better. Rent one for a couple of days, and I'm sure you'll reach the same conclusion.
