Standard sized guitars are simply too bulky for some people. Young students may find them hard to carry, especially on a school bus packed tight with kids. Older, people, and those suffering from a disability, may just not be able to deal with the length and girth of a guitar case. Handling the guitar itself may not pose much of a problem, but the cases alone can present a major inconvenience when taking a plane, a public bus or traveling in a car. Storage at home can be a problem too.
