Even though there are hypothetically several different ways to begin touring the Computer Museum of America, so far, my experience has been that people like to start with the personal computers first. Perhaps it's the most popular start because it's what people connect personally with and remember most. Perhaps it's most popular because there are so many interesting things immediately visible down the hallway compared to the relatively empty rotunda. Most likely though, personal computing is the most popular start because it's simply closest exhibit to the entrance. Thanks to ASIMO the robot welcoming guests in, (and blocking direct access into the Rotunda while doing so), it's literally impossible to enter the museum without at least walking past the Datapoint 2200, starting visitors down this path.
