easy to learn and use

Easy to learn refers to software that is well designed and capable of being used right away without having to wade through documentation. If you make the program work with little effort, it is easy to learn.

Easy to learn implies easy to use right away, but it does not imply easy to use after weeks of using it on a daily basis. The menus that coddled you in the beginning often become tiresome when used constantly. Some rare programs have a macro recorder that lets you store a series of menu selections and execute them automatically. This should be standard procedure however.
