Script objects are an essential part of AppleScriptObjC development, of course. Apart from that, there's nothing you _can't_ do without script objects; however, they do make certain tasks much easier. The two major uses are libraries and object-oriented programming, both of which are powerful tools for organizing large or complex code.
Libraries make it easy to reuse general-purpose handlers from script to script without having to copy and paste them each time - a common source of code clutter and a maintenance headache whenever you have to change something.
OOP allows you to parcel up complex data structures with the handlers that manipulate them, making them simpler to work with and cutting down the number of 'moving parts' in your code that you need to think about at any one time.
(I'll have a lot more to say on these subjects in a couple of months, so watch this space, etc.)
