Do you get good interest rates anywhere? Last time I checked at banks I think checking accounts had .06% and even a long term CD was around 0.9%.
I'd be better off just playing the market at that point (or using something like betterment/wealthfront to hold most money).
Simple is nice because the interface/app are solid and they have incredible customer service. The only other thing I'd want from them is a decent rewards credit card.
