Hardware that can run the latest Apps without being slow is expensive. Hardware that can do all the things those Apps do if programmed more responsibly is cheap.
I want to build ultralight software that is runnable on dirt-cheap hardware. I want to build new hardware that is inexpensive but still useful and pleasant to use.
I feel like we're not far away from this, and that all we need to do is push for it to become more popular an idea.
