Experimental products (especially in the software world) usually go through extensive quality assurance (QA) testing internally before shipping to customers. This involves a specialized team of bug testers sifting through the product to ensure it will function properly on most/all devices. A public beta test is usually released to test the quality/stability of the product on a much wider scope, to gather feedback on the product from a more realistic userbase, and also sift out the more device-specific bugs, as well as any issues the QA team might have missed. In other words, the beta testing stage is (most of the time) only released to people once companies like apple are sure its reached a point of usability.
