Why insist that everyone has to like exactly the same things you like? The increase in battery capacity is a real thing, and is driven by mobile phone technlogy. Mobile phones have made cheaper, more capable desktop machines possible as well, but given the choice, people tend to spend more money to get the mobile phone or an update to an existing one.
Mobile phones? EV batteries?
Heck, most mobile phones with the best batteries, only get a few hours of power, and to get all day service from those batteries, you better not do anything other than talk and text. Same with EVs, where most EV vehicles can only do less than 100 mile range out of a charge.
So, no, not ready for prime time.
