Cheap devices that run Windows 10 are also available, like the eight-inch NuVision tablet, and music apps can be downloaded from in the Windows Store. Apple’s least expensive model in its iPad line is the $329 Wi-Fi iPad with 32 gigabytes of memory; the company’s own GarageBand music-creation program is free, and the App Store has other possibilities. Buying a refurbished tablet is another way to keep costs down.
