qqp question1: Should I buy Sphero 2.0 or Mip robot? Please do not recommend others, you are forced to choose between these two, and keep in mind about the price too. question2: If I keep choosing not to fully think about a concept or grab onto it when it appears in my mind while I am reading or doing something else, am I damaging my brain's ability to understand and act on those things in the future?
