The iMovie has some great new features like slow-mo and fast speed, I like the guitar and piano lessons that come with it

Note: there are 9 free introductory piano lessons, and 9 free introductory guitar lessons (the lessons feature an acoustic guitar, but they appear to be useful for learning both acoustic and electric guitar ... same principles).

These lessons look _better than real lessons_.

That will depend on what lessons become available

If you want to learn piano or guitar there are 8 free lessons that you can download.
