+1 for Monosnap. Best UX in this category. Their arrows are very visually pleasant, guiding viewers' eyes to where you want them to look. No other software seems to have this type of arrows.
This is giving wayyyy too much credit to a sub-reddit that's all about poking fun at the trading game, and each others. Please don't throw your money away following them.
a technically well-versed audience like this HN crowd is not really the customer base for computer equipment from Costco. In keeping with their product offering approach, Costco is catering to the people too busy and/or don't find it fun to evaluate computer equipments. What their customers know is that what Costco offers is good enough and pretty good value. The liberal return policy helps ease customer concerns about making equipments work. Looks to me like Costco is doing it pretty much right.
Their point is that you don't need to pay/donate money, only using their product for something you need anyway, ie. search, and generate funding for planting trees.
