As usual, you upgrade by selling your old device on eBay, and using that money towards a new one. The other method is handing it down to someone else. No fan, low power, low heat, SSD, that should all help with longevity.Several multiples faster and almost twice the battery life at the same price, yet it seems like all I see are complaints about longevity and upgradability... some people will literally never be happy, and it's 100% by their own choice.
