This happened in New Westminster in BC... they shortened the yellow light to catch more people. It was a nice little conspiracy that wasn't widely reported. Someone timed the camera light yellows vs non-camera light yellows... the camera ones were all shorter.
True, but the battery they're using is 10,000mAh, or (likely) about 110 Watt-hours... it's going to be big and heavy no matter which Li chemistry you use.
Li-ion cylindrical cells -still- have the highest energy per weight and energy per volume. There are so many made by so many companies that cost is lower and performance is better.
My experience is a tablet uses about 140Wh per day in full use (stock trading), which would jive with the comment about the electrovaya tablet "only" giving 6 hours instead of 8.
I would suspect that after 8 months of use, this tablet would have similar performance to a Fujitsu or Motion tablet of the same age as Li-Polymer degrades faster than Li-ion.
Lithium ion is far superior to Li-polymer, Electrovaya's polymer is well known for only getting 200-300 cycles, only a year of use for business... Li-ion typically gets 500 to 1000 cycles with a nicer fade over the life cycle.

Just proves it's all about a revenue stream.
