There are advantages to standing instead of siting, but since you cant do that ALL the time in order to enable it you need motorized table legs. Or at least thats how I did it.
I just put a small table on top of a bigger table. Switch the place of the keyboard/laptop/book. It seems to me that if you stand enough the expected utility of a super chair is pretty low, maybe even negative if it makes you sit more. I still dream about getting one to be honest though.
On ChrisHallquist's post extolling the virtues of money, the top comment is Eliezer pointing out the lack of concrete examples. Can anyone think of any? This is not just hypothetical: if I think your suggestion is good, I will try it (and report back on how it went)
I care about health, improving personal skills (particularly: programming, writing, people skills), gaining respect (particularly at work), and entertainment (these days: primarily books and computer games). If you think I should care about something else, feel free to suggest it.
I am early-twenties programmer living in San Francisco. In the interest of getting advice useful to more than one person, I'll omit further personal details.
Budget: $50/day
If your idea requires significant ongoing time commitment, that is a major negative.
