Your also giving up better trade execution ie paying more for shares. Robinhood is good for getting your feet wet but people should switch brokers as soon as possible.
But I execute maybe, 4 trades per year. E-Trade / Ameritrade / Scottrade are good enough, and offer me Options trading and other useful features.

Yea valid point. I make 2 to 4 trades a week so IB makes sense for me. Plus I signed up before I was 25 so my monthly fees are still only $3 instead of $12. Plus I do enough trades that my monthly fees are waived.
